Not very funny, and since the only daughter with her was Willow it implies that Elliot Spitzer is a pervert that was trying to contact her 14 y/o daughter. Pretty stupid joke to make, but I'd have a hard time arguing that the joke is implying that Willow is a prostitute. The stupidest thing about that joke is that keeping Spitzer away from their daughter would not be tough at all for either Sarah or Todd. Either one of them could easily kick Spitzer's butt so hard that he'd never bother anyone's daughter again.
