Kimmel Vs. Leno Feud Reignited (Video)

Kimmel strikes back at Leno's crack that the ABC late night host wears a toupee and dyes his hair

Jimmy Kimmel doesn't get mad, he gets even — which led to another funny entry in Kimmel's ongoing late-night spat with "Tonight Show" host Jay Leno.

After Leno did a "Tonight" Valentine's Day gift segment Thursday that suggested Kimmel wears a toupee and dyes his hair black, Kimmel responded on Monday's "Jimmy Kimmel Live" with a segment in which he did his best Leno impersonation to reel off a series of lame jokes. Like …

"The Grammy show lasted three and a half hours last night … before it was over, Kim Kardashian married half of the L.A. Clippers," and …

" … the Beach Boys are so old, I wasn't sure if I was watching the Grammys or the Grampys."

The latest Kimmel/Leno dust-up follows their tense and hilarious January 2010 exchange during the "10 @ 10" segment of Leno's now defunct "Jay Leno Show," in which Kimmel poked fun at Leno about his NBC "Tonight Show" brouhaha with Conan O'Brien.
