A re-post:
I must confess I always thought the Rascal's Groovin said "You and me and Lesley" - figured Lesley was either a dog, or a reference to a menage a trois, or his little sister. Neo's "Sugar fried honey butt" for "Sugar pie, honey bunch" (Four Tops) gave me a giggle. There is a website devoted to mondegreens: Kiss this guy.com. Also, "A girl with colitis walked by" was a pretty good one, too, Sippican: a good nose for them gastro-intestinal mondegreens.
My favorites from my own ears are "Lead us not into Penn Station, but deliver us from evil," and "Rain, rain, go away. Come again on Mother's Day."
And the Stones' "Hey, hey. You, you - get off of my cow."
