Michael replied, "Just a minute. I have to go pee."
"That would be rude and impolite, Michael. What about you Sherman, how would you say it?"
Sherman said, "I am sorry, but I really need to go to the toilet. I’ll be right back."
"That’s much better, but it’s still not very nice to say the word toilet at the dinner table. What about you, little Johnny? Can you use your brain for once and show us your good manners?"
Little Johnny sighed, and replied. "I would say: Darling, may I please be excused for a moment? I have to shake hands with a very dear friend of mine, to whom I hope to introduce after dinner."
Funny short joke
