You shouldn't date your friend's significant other.
Barry and Joanne have been married for nearly five years.
Barry's friend, Sam, wants to go away for the weekend with Joanne.
Knowing that Joanne loves comic books as much as he does, Sam asks if she's like to join him for a Comicon convention that's taking place at a local hotel.
While having dinner at the hotel, Sam puts his hand on Joanne's knee and asks her to come back to his room.
Joanne is thrilled to join Sam at the convention because Barry hates attending Comicon.
Joanne is horrified and tells Sam to leave her alone.
