So when we caught up with Mr. Cosby at the American Comedy Awards where he was honored with the Johnny Carson Award, we got his take on his friendship with Fallon. See why he says "Jimmy is honest, and a person you like" in the video above.
Bill also revealed that Jimmy helped him out—by accident! That time that Jimmy jumped on Bill's back? It actually made Bill's back feel BETTER. There's only one solution here and that is a weekly chiropractor appointment on The Tonight Show. Let's make it happen, guys.
Watch Bill get honored at the American Comedy Awards, Thursday at 9 p.m. on NBC.
