The milkman stopped at her house on his usual route. The note attached to the milk carrier at her front door said to leave 10 quarts of milk.
Wanting to verify the quantity, the milkman rang her door bell. When she answered, the milkman inquired if she did indeed want him to leave 10 quarts of milk. She answered in the affirmative.
So the milkman asked "Do you want it pasteurized?"
She responded, "Oh no, I just want it past my knees. I want to take a milk bath."
Note: This is the kind of stuff we tell each other at the senior center while we play cards.
