Well, as long as we're basing our snark on allusions to classics...
...it's hard to beat Bernie Marcus's ad-lib line from an MSNBC interview last year, when he was explaining why Team Obama's optimism about the economy was catastrophically misguided: "Geithner does to small business people what Debbie did to Dallas."
A year later, back on MSNBC and reminiscing about the aftermath of that ad-lib, he muses ruefully, "I got a lot of heat for that. My wife said, 'When did you watch that film??' I got in trouble."
(That interview is well worth watching, by the way. HT: Ace.)
