I was going to do a toon about his gaffe, but Mr. Daiker beat me to the punch in the Gargoyle Leader.
But here are some of the lines:
Obama, “It’s good to be in Sioux City”
Audience member, “I hope he knows what country he is in?”
or
Obama, “It’s good to be in Sioux City”
Audience member, “Great. Another presidential candidate the doesn’t know their ass from a hole in the ground?”
or
Obama, “It’s good to be in Sioux City”
Audience member, “Well, both cities suck, so close enough I guess.”
