Ha ha, yea... it's from the SNL skit where a fake (and funny) Sean Connery was on Jeopardy and said the following (read it out loud in your best Sean Connery voice):
"Well ya were wrong, ya mountebank. I poshe a conundrum to ya, a riddle if you will. What'sh the differensh between you and a mallard with a cold? One'sh a shick duck... I can't remember how it endsh, but yea, ya mother'sh a whore."
I dunno... can't shake hearing him say it...
