universal ethnic. or, this happens to me a lot.

Two carpenters are tearing down the front door of my apartment.
One of them looks at me in the hallway, and asks, Are you Greek?
The other turns around, looks at my beard, and says, No, he's Egyptian.
I'm Indian, I say.
You're Jewish? asks Carpenter 2.
No, Indian.
Ah.
