I enjoy how as soon as Jim appears, Martin becomes a lot more normal and sensible, almost like he's thinking "right, well there's no way I can compete with this weirdness"
He bugs the family because he wants friends and he can’t see that what he’s doing is annoying. Anyone would find it hard to put a restraining order on someone as lonely as him.
I love this show and Martin is my favorite. But seriously I will never understand why he didn't beat the crap out of Jim for ruining his family dinners and creeping on his wife
