You shouldn't get into questionable friendships when you're married.
Dave and his wife are in Las Vegas when a prostitute approaches them and asks Dave if they wanna hang out.
Dave wants to respond to the prostitute's request.
Dave tells the prostitute that she should find someone else to hang out with as she's not their type of friend.
Dave tells the prostitute that it's a great idea, and they should all go hang out a while and get to know each other.
Dave's wife is happy that Dave understands the standards she holds their relationship up to.
Dave's wife is angry that Dave doesn't see the problems that could arise out of that friendship and doesn't trust Dave's judgement.
