Paul is an "average" man who, aware of his lack of allure, uses his dog, Pepper, to get dates. He is smitten with Will, and constantly refers to him as "sexy" and "gorgeous" (much to Will's annoyance).
When Jack loses his dog, it is later revealed that Pepper is trained to run away so Paul can get dates out of pity.
He is referred to by Will as "needy and desperate". 
- It is implied that he is a doctor.
- He speaks sign language (which he uses to tell Will he loves him.)
Pepper, you're back! Oh, you must've climbed up the fire escape and...pried open the bedroom window. — when Pepper "returns", Mad Dogs and Average Men
