One of the most ridiculously petty arguments ever appears to have broken out over Twitter after what was deemed by a seemingly overly uptight Don Lemon to be a less than courteous handshake by actor Jonah Hill in a hotel recently.

The pair have been bickering over what appears to be precisely nothing over the social networking site, with Lemon spilling his rage into an appearance on CNN. "Said hi to @jonahhill in hotel. Think he thought i was bellman. Didn't know his name til bellman told me. A lesson to always be kind” grumbled Lemon on Twitter, an indication that had racial undertones. Hill was less than impressed, replying "I said hi what do you want me to do move in with you? I was in a hurry. Didn't realize you were a 12 year old girl. Peace." adding: "I walked out of the restroom and found you waiting for me. Shook hands, said hi and was on my way. Sorry if you found that rude."

Lemon then went on CNN and continued his rant: “Jonah Hill doesn't owe me anything, and he may have been having a bad day ... but Jonah Hill treated me like the help” he fumed, though he did admit he was squeezed on the hand by Hill. He claimed however that it was a “wet handshake", continuing: "Normally it doesn’t bother me, but I was done ... because I’d been taught by mother to always be kind to people.” What a bitter Lemon.
