Really? How so? Other than the fact that he's in a much later phase of his life, I don't see how he's a match for Sarah in anyway. Maybe as a father figure or something. I don't know what their exact ages are on the show, but based on the ages of the actors involved, I would say Mark is about the same amount younger than Sarah as Sarah is to the Romano character, so there would still be a decent age gap. Sarah getting together with that grumpy old man would be extremely bizarro to me. Not that they couldn't spark up some sort of unique friendship.
