Last night on the debut episode of The Tonight Show Starring Jimmy Fallon, the host Jimmy Fallon decided to call in a $100 bet made with a friend of his that said he’d never be the host of The Tonight Show. As it turns out, Fallon had a similar bet with a number of different friends, including but not limited to Robert De Niro, Kim Kardashian, Joan Rivers, and even Lady Gaga, and they all paid a visit to the set to cough up the dough.
