Dinosaur Day with William Hayes.
Over the Summer during HBO's Hard Knocks with the Los Angeles Rams, defensive end Williams Hayes revealed that he flat out does not believe in dinosaurs. No amount of fossils could convince him otherwise.
When the show aired, Kimmel offered to take Hayes to a museum to persuade him that dinosaurs aren't just some "hoax" and the two finally linked up to make it happen.
Dressed in their finest safari gear, Kimmel took Hayes to the Natural History Museum in LA for a hilarious field trip to find once and for all that dinosaurs did, in fact, roam the Earth.
