The Wet A$$ Hour
When Helen Kruger finds out Frank is a cop he tries to explain it away. When he's at a party and says he's a cop it's like he's got leprosy. Then he says angrily "in the wetass hour, I'm everybody's daddy!" I'm surprised no one else has asked this. But the way I took it, the 'wet ass hour" is when they are in trouble and in need of a cop. Is that your take on it?
