Do you really want to go there, dude? Do you really want to mock Obama for having "skinny legs" and "scrawny little arms"? Have you looked at your guy, lately? Or for that matter, yourself?
In case you hadn't noticed, this isn't a pissing contest. Leave it to a former bodybuilder to reduce this to body parts instead of intellectual ability, temperament, character and judgment. But don't despair, Arnold. If you're really nice to Maria, maybe President Obama will still invite you to a friendly game of one-on-one at the White House basketball court and kick your little girlyman ass!
(Or he can just embarrass you at the beach)
