I'm a military guy, maybe I should start practicing my PAs now...
Anyways, I heard this one while flying on American Eagle a few years ago. "Ladies and genntlemen, if you look outside on the left side of the aircraft, you'll notice the town of Wedlock, Texas. Mary (our flight attendant) was born and raised just outside of wedlock."
Some people got it, most people were actually looking for the town. I thought it was quite clever.
