Kinda Weak. Hardly a "destroy." A moderate zinger at best. The whole show is centered around unemployed actors, politicians and and ex-athletes. How hard is it to throw out a has-been joke? Kimmel's done better.
How about "Clarissa Explains It All"? MJH has been around for 20 some odd years now- basically playing the squeaky clean america's sweetheart role.
Kimmel was a dick. I think he realized that right after he said it. Be interesting to see if he or she brings it back to some sort of comic skit like thingy...
