"And so simple that I found lots of more or less similar stories..."
It is a hallmark of urban legends.
This story seems to originate with the case Bodine v. Enterprise High School, which involves a 19 year old on the roof of a high school who fell through a skylight covered with tar.
It is a veeeery old thing.
And so simple that I found lots of more or less similar stories, but not this particular one. (but found lots of interesting stuff on google...)
