Fallon Mocks Leno's Denim Obsession During Hilarious Thank You Notes Segment (VIDEO)

"It'll be fine."

That's what Jimmy Fallon said under his breath after doing a one second impression of Jay Leno following a punchline involving the oft-maligned late night host.

It turned out to be the highlight of one of our favorite "Thank You Notes" segments to date...every single joke was a winner, and Jimmy delivered them with his signature guileless charm. Ranging from women complaining about men leaving the toilet seat up to Hershey's Kisses not having a more awkward anatomical name, the segment was great fun all around. But the good-natured jab at Leno (and as we all know, a crack against Leno is a crack against NBC itself) sealed it.

Watch the whole segment below and let us know in the comments if you have any explanation for Leno's weird denim thing. We get the cars, but the head-to-toe denim eludes us.
