I would like to call your attention to Shelly Berman’s Cleans & Dirtys. He makes these observations:A Big Boob is a Clean, but Two Big Boobs is a Dirty.
Hotel is a Clean, Motel is a Dirty.
A little Ahead is a Clean, but a Little Behind is a Dirty.
Tarzan walking with Jane is a Clean, but Tarzan swinging with Jane is a Dirty.
Henry is a Clean, Clyde is a Dirty.
Lake Superior is a Clean, Lake Titticaca is a Dirty.
“Did you go to the Y and swim?” is a Clean, “Did you go to the A & P?” is a Dirty.
“Yes, my child” is a Clean. “Yeah, Baby,” is a Dirty.
Then there are Clirtys…
