This is Bill Gates. A very happy Bill Gates. He is obviously so happy to show off the CD-ROM.

Who doesn't know Bill Gates? Yup, the business magnate who happens to be the richest person in the world! Well to start not many people know that his full name is actually William Henry Gates III and "Bill" is just his nickname.

CD-ROM is an acronym that stands for Compact Disc Read-Only Memory. It's basically a CD that can be read by a computer through its optical drive. This particular photo was taken in 1994 -- a fruitful year for Microsoft.

In that very year, a number of products on CD-ROM were released for MAC and Windows. It includes the 1994 Edition of Encarta, Cinemania 1994, Bookshelf 1994, Windows Sound System 2.0, and Office 4.2 for Windows, among many more.

Oh no, he's not sick. He's not on drugs either. This is what you will actually look like if you've been exposed to tons of laughing gas.

Laughing gas technically isn't any laughing matter. It's got health hazards. Too much exposure to it can cause mental and manual impairment, oxygen deprivation, vitamin B12 deficiency, and infertility among many others. What we're trying to say is -- too much of it can actually kill ya!

Scientifically known as nitrous oxide, it is a chemical compound that's colorless. It's an odorless gas which is non-flammable. Nitrous oxide has a handful of medical uses. It has potent analgesic and anaesthetic effects.

Yes, we know it is something that must be taken seriously. But you might wonder, why do they call it laughing gas? Well, inhaling it gives you what they refer to as a "euphoric effect". It's that kind that dulls your awareness and gives you that calming effect to that point that something you end up with a giddy feeling that eventually leaves you laughing.

Do you see any familiar faces? Yes, Adolf Hitler was the best man at the wedding of Joseph and Magda Goebbels.

Now you might wonder, who in the world are Joseph and Magda Goebbels and why is Hitler the best man at their wedding? Paul Joseph Goebbels was actually one of Hitler's closest associates and his devoted friend. They were so close that in Hitler's last will and testament, Joseph was appointed Reich Chancellor of the Nazi Party.

As everyone knows, Hitler committed suicide on April 30th of 1945. With the same principles in life, people expected Joseph to likewise take his own life rather than to be taken by the enemy. But no, he did more than that. On the night of their death (yes, their because he committed suicide with his wife since she was also a member of the Nazi), he asked a dentist to inject their children with morphine to make them unconscious. Later, an ampule of cyanide were crush inside of the children's' mouths. So yeah, he literally took his family with him to the afterlife.

Yes, that is who you think it is. Terminator himself! This is Arnold Schwarzenegger during one of the body building competitions he joined.

Arnold Alois Schwarzenegger is undeniably one of Hollywood's biggest stars... and not to mention one with a tongue twister last name! Who would ever thought that a professional bodybuilder from a small village in Austria would be where he is now? It's literally a "rags to riches" for this Austrian who migrated to the United States in 1968 to live the American Dream.

He started weight training at a young age of 15. He then won Mr. Universe when he was 20 years old. Not only did he win Mr. Universe, he also won Mr. Olympia seven times. So naturally, he caught the eye of those in the film industry.

His breakthrough film? Conan the Barbarian in 1982. But of course, he is credited for the iconic role of The Terminator which led to a franchise with a total of 4 installments. He also starred in Commando, Predator, Total Recall, Kindergarten Cop, and much more.

In case you didn't figure this one out -- this is actually the mummy of King Tut. Yup, the infamous Tutankhamun of the 18th dynasty of Egypt.

The modern world barely knew of the boy pharaoh Tutankhamun until archaeologist Howard Carter discovered his tomb in 1922. Now this is where things will get a little crazy and we assure you that just like us, the things we're about to tell you will totally remind you of Brendan Fraser's The Mummy franchise.

So apparently, genetic testing has confirmed that King Tut comes from the lineage of Egypt's great pharaoh, Amenhotep II. At an early age of 9, he succeeded to the throne. Yes, he was just 9 years when he took power. Crazier enough is that on the same year, he married Ankhesenamun. Ankhesenamun was actually his half sister, the daughter of his father by Nefertiti. King Tuth died at age 19. He was burried in the Valley of the Kings.

What else makes King Tut popular? Three words -- "the mummy's curse". It was said that many unfortunate events happened right after the tomb of King Tut was discovered. According to the legend, anyone who dared to open his tomb would suffer the wrath of the mummy. All the hype started with the death of Lord Carnavon (the person who financed Howard Carter's expedition). What was scarier was that the exact moment he died, all the lights in Cairo went out.

No, this guys hasn't gone crazy. He's actually paid to do this. Say hello to your friendly neighborhood helmet tester. Yep, this is a football helmet prototype tested by man

Back in the days, there was no headgear for football. For some weird reason, players grew their hair long on the belief that it would protect their heads. It wasn't until 1896 when football headgear was introduced. George Barclay gets the credit for it. He made this piece of headgear known as "head harness". Well this technically didn't look anything like the helmet we have now as the head harness was literally just 3 thick leather straps that was worn as harness around the head.

Innovations were introduced in the following years. In the 1920s, the helmets were widely used in football and they were made out of leather. However, these provided very little protection as these weren't sufficiently padded. They were also very uncomfortable because they absorbed a lot of hit.

So yeah, whoever the dude in the photos is -- he needs to be given credit. That's one huge risk to take for the future of the helmet!
