Conan already skedaddled if he can't do The Tonight Show at 11:35. Jay reneged on his retirement once, but he can't possibly keep doing this for much longer. What does that leave NBC with? Jimmy Fallon. Uh-oh.

Here is a compilation of Fallon inappropriately laughing on SNL AND on Late Night With Jimmy Fallon.
