This joke is one my sister made up. I had had too many rum cocktails and laughed til I cried. The amazing thing is I remember the joke despite the booze:
What do you call someone from Venice who can't see?

Like I said, I was tipsy... LOL!
Ha, thanks for the joke. I'd call it a dad joke, but a sister joke works. For some reason they always make me smile.
