So a middle aged man has had ED issues & has gone thru all treatments & drugs to no avail. His wife contacts a medicine man on the reservation who has a cure. Sends her husband to see him.
The medicine man says "I have cure" & pulls down a bowl full of powder.
"Powerful medicine" he says & scoops a couple tablespoon's into a bag & hands it to him. "Now...listen carefully to my instructions. You put 1 teaspoonful into a cup of water-say one, two, three & drink. You will instantly be ready to perform."
"Great" says the man & heads for the door-then stops & turns back & asks the medicine man "how do I make it stop?"
"Ahhh yes-good question- say one, two, three, four & you will not be able to use this again until the next full moon."
He returns home & invites his wife into the bedroom-mixes the brew-strips-says one, two, three & drinks. I works like a charm. "Whooo-hooo!" his wife says excitedly & begins to strip also. While doing so, she asks him "What was the one, two, three, for?"
And the moral of the story is: Don't end your questions with a preposition because it will leave a dangling participle...
