How about drinking and walking? You could, I would think, cause an accident by stumbling out onto the road, or crossing the street without looking. When the bars are let out, there are all kinds of drunken folks plying the streets.

Maybe, if you party too much, you should just lay down where ever you are until you are sober. Just to be safe.

And don't think about having sex just because you are laying down. You might catch an STD, or an unwanted pregnancy.

And no smoking!!! Don't you know that's bad for you?!?!?!
