Jerry Seinfeld stars in a 2012 Super bowl commercial for Acura that has just leaked, and it's funny - until another comedian shows up.

Seinfeld wants to own the very first Acura NSX, and he'll stop at nothing to get it. But the very unfunny Jay Leno, who's also an avid car collector, swoops in. Boo.

This would have been a grand slam, if they would have used Wayne Knight (who played Newman, Jerry's nemesis on "Seinfeld") rather than Leno. Check it out, and see if you agree.
