And then there is this guy

He was watching a donkey eat some figs and cried out: "Now give the donkey a drink of pure wine to wash down the figs".

Thanks. I can now sleep easy. It was kind of anticlimactic. The joke isn't funny. If your going to be killed by a joke, at least make sure its funny.

You're looking at it the wrong way. Imagine how high this guy must've been to actually die from such a poor joke... unless "donkey", "figs" and "wine" have a completely different context in this here joke.

My guess is that it's a sexual double entendre. Like in French, to "make a map of France" is something dirty but you might not guess it.
