We don't yet know when Royal Pains will air its season finale. But we do know the episode will be funnier than the typical installment of this USA hit.
That's because comedian Jim Gaffigan will guest star. As first reported by TV Guide, Gaffigan will take on the role of a patient Hank must diagnosis. Look for this character to be a park ranger who undergoes a major personality shift, without any clue for the reason behind it.
Royal Pains is currently on hiatus. It will return later this year with six episodes to wrap up the season and you can catch up on whatever you've missed so far in our Royal Pains reviews section. Enjoy!
