Anyone remember the episode of Seinfeld, where Jerry accuses his dentist, Tim Whatley, of converting to Judaism just for the jokes? Ladies and gentlemen, lets have a round of applause for Senator John 'Felafel' Kerry."So who said I don't have the matzoh balls to be here?" Kerry asked at a St. Patrick's Day Breakfast.

The AP notes that after taking a few jabs at the hoopla surrounding his Jewish and lack of Irish heritage, "he ended his brief appearance onstage by singing a parody of 'If You're Irish Come Into the Parlor,' entitled 'If You're Yiddish Come Into the Parlor.'"

On the show, when asked if it offended him as a Jew, Jerry replied, "No, it offends me as a comedian."
