I think everyone can see that this is not a smart move.
I don't think we need to warn people about it ;-)
I'm sure there's some 16 year old working on a Beetle and might think of trying it.
Lucky for him the belt was very loose (probably on purpose)...
Ya think?
Just remember... STUPID SHOULD HURT.
BTW... just recently a long time VW mechanic out in California got sloppy when working around a running engine. He got his hand caught in the fan belt and lost his index and middle fingers.
Sorry... but safety first. Let's not give anyone and help.
