Bradley Cooper appeared on "The Tonight Show" with Jimmy Fallon on Friday to talk about "The Elephant Man," which is a Broadway show that the "Guardians of the Galaxy" actor starred in. In fact, Cooper had the lead role in the show.

Fallon then gave Cooper an Eagles visor that was topped with a spiked hair wig, poking fun at how the actor looked like last week when he was spotted at Heathrow airport in London. To make the segment even more hilarious, Fallon also took out another one for himself and wore it as well.

True enough, the duo could not stop themselves from laughing. They just could not hold it together for more than several seconds, even failing to finish a full sentence because they just could not talk and look at each other without bursting into laughter. The audience watched on and could not keep themselves from laughing as well.

Apart from the funny interview, where they both could not even get a word out without giggling or laughing, they also played a round of Fallon's famous Egg Russian Roulette. They smashed eggs on their foreheads, not knowing which ones are raw and which ones are hard-boiled. Surprisingly, for the first time ever, the game came down to the last two eggs.

It was a showdown that was filled with suspense, as they braced themselves for the eggs that they broke on their faces. They each took turns choosing which eggs to use, without knowing whether or not they would end up getting wet with the yolk or not.

Seeing the funny side to Bradley Cooper was refreshing, especially after his "American Sniper" trailer was far too intense. Seeing the amazingly handsome actor smile and laugh, who has been more known for his serious roles in various movies and blockbusters, was heartwarming.
