No they don't at all but just in case you THINK they do, remember Rocky sez:
"
I like big butts and I can not lie
You other brothers can't deny
That when a girl walks in with an itty bitty waist
And a round thing in your face..."
oh Rocky, you naughty boy!!!
Edited! Had a major typo in the Title Box -- an "x" in the place of a "z" -- must have been a Freudian slip!
