Usually comedians are standing up on a stage making people laugh so hard that they fall over.  But sometimes, as in Jon Lovitz’s case, they’re knojohn-lovitzcking people over by other means.

Last week Jon Lovitz beat the crap out of Andy Dick.  It all happened at the legendary Laugh Factory, where the owner, Jamie Masada witnessed the whole thing.  He told press, “Jon picked Andy up by the head and smashed him into the bar four or five times, and blood started pouring out of his nose.”

The feud has been going on ever since beloved comedian Phil Hartman was killed by his flipped-out wife.  Lovitz maintains that it was Dick that set the whole thing into motion. “Andy was doing cocaine, and he gave Brynn some after she had been sober for 10 years. Phil was furious about it – and then five months later he’s dead,” Jon told press.

Then, last year, there was a strange exchange between Dick and Lovitz.  While dining out with friends, Lovitz says Dick came to his table and started trouble.  “He looked at me and said, ‘I put the “Phil Hartman hex” on you – you’re the next one to die.’ I said, ‘What did you say?’ and he repeated it. I wanted to punch his face in, but I don’t hit women.”

Then last week, the two encountered each other again.  And Jon was looking for an apology from Dick.  Instead he got more lip.  When Lovitz asked Dick to say he was sorry, Andy replied with “do you want to be in my movie?” That was the last straw.  “I grabbed him by the shirt and leaned him over and said, ‘I don’t want to be in your movie! I don’t want to be in your life!’ I pushed him against the rail. Then I pushed him again really hard. A security guard broke it up. I’m not proud of it . . . but he’s a disgusting human being.”

There’s no word from Andy Dick, or any news of charges being filed.
