Alex, that's no joke.... such a thing actually happened. Not exactly the same reasoning, but; My dad was born in Bulgaria and raised in Turkey. One day while traveling through the countryside with his dad, they somehow happened to surprise a couple of muslim women who were in a field and who didn't have their faces covered as they customarily do. The ladies panicked and raised their skirts up over their faces, only to reveal that they wore NO undergarments.... My dad and grandpa were amused!

Not exactly a jewish joke, but my dad and grandpa are jewish... Margo
