When Bradley Cooper [1] stopped by The Tonight Show on Friday, he and Jimmy Fallon [2] ended up with a serious case of the giggles, and they just couldn't get it together. The pair played Egg Russian Roulette [3], and all the flying yolk had them cracking up, but they couldn't stop laughing during the sit-down interview, either. For one thing, they were sporting that silly visor look Bradley debuted earlier this month [4]. And for another, every time Jimmy tried to ask Bradley serious questions about The Elephant Man, they ended up in tears because they were laughing so hard. Just try not to crack up watching their hilarious interaction above!
