My wife is Better

Jake and his buddy Fred visit a brothel. Jake goes into the room with the prostitute first while Fred waits outside.
When he's done, Jake closes the door behind him and says: Don't waste your time. My wife's better.
But Fred goes in anyway. When he emerges 15 minutes later, he shakes his head in disappointment and says:
 

Damn, Jake, you were right. Your wife is better.
