Without missing a beat I said “I knew a girl once with three sphincters.”
Everyone laughed to beat the band, but my buddy was “in” on the joke. He said after the laughter “Everybody has three?”
“Three in the digestive system. Esophageal, Pyloric, and Anal, everyone’s favorite.”
Weeellll, actually, I once knew a young lady that had three. They weren’t lined up horizontally as in that movie. Instead she had the “extra” one a few inches below her left breast. It wasn’t as large as the others and she was able to cover it up with a special bra that just mashed it down flat.
After that encounter I looked the subject up and it’s actually pretty common. Most people on’t even know what it is, thinking it’s just an oversized mole.
You missed one: the sphincter of Oddi. So your girl was even more sphincter-iffic than you realized.
