One thing about Leah is that right or wrong, she won’t back down. Her appearance on Howard Stern was a good example, back when Artie Lange was still on the show. She was busting his balls, and when (either he or Howard) defended him by saying he was in movies, Leah says “Really? Movies? What movies have you done?”
So Artie says Old School, to which Leah went for blood. Really? You were in Old School? She sets him up, getting him to state it outright, then lowers the boom. “That’s funny, Artie, because I was in Old School and I don’t remember you there at all.” She railed on him for several minutes for pretending to be in Old School. What a dolt; at least pretend to be in a movie Leah wasn’t actually in, right?
Of course Artie was, in fact, in Old School, and no matter how much Artie, Howard, Robin and Fred explained to her that Artie was in it she not only didn’t believe them but kept giving Artie shit for pretending to be in Old School.
