Here's the short, cleaner version of the story.
A friend worked in a pizza place what was open late at night.
It wasn't in the best area of the city and attracted a lot of drunks after the bars closed (last call is at 2am).
The guy was a short guy who told my bud that if anyone came in and wouldn't leave, he should "hit 'em with the mitt" at which point he produced a large oven mitt from under the counter. The end was full of ball bearings.
My buddy says that if you swung that thing hard enough, you'd kill someone.
After he was told about the mitt, the owner would be working some nights and would tell him that indeed, he did hit people who wouldn't go.
At times, when someone came in, the owner would look to the mitt as if he wanted to bean the guy just because.
I think that's an exaggeration, but the mitt is not.
The pizza place is long gone now. The mitt only lives in our memories.
I like the clean version, Marc. I can easily imagine how it could be "dirtied" up a bit, but I can't imagine that would add anything to the story.
