It looks like this weird beef that's erupted between Jonah Hill and Matthew Morrison isn't done yet. Hill first brought it up on 'Late Night' (Weeknights, 12:37AM ET on NBC), talking about how Morrison apparently used his name as the punchline of a joke.

He then turned to the camera and called Morrison out, threatening him to come and face him. Well, on Monday night's show, 'Late Night' got a response tape from Morrison on the set of 'Glee.'

"Jonah, pick a date and I will meet you on 'Late Night with Jimmy Fallon' and we will settle this like men," he said angrily. "Because nobody messes with someone from musical theater!" At this, he started dancing around gleefully.

We cannot wait for their inevitable confrontation on 'Late Night.' Made up celebrity beefs are a lot more fun than real ones, aren't they? Especially when they're as random as this one.
