If you were on a date having dinner with a nice young lady, how would you tell her that you have to go to the bathroom?

A Teacher trying to teach good manners.... then asked his students this Question:
Michael if you were on a date having dinner with a nice young
lady, how would you tell her that you have to go to the bathroom??
Michael:"Just a minute, I have to go pee.."
Teacher: That would be rude &
impolite.. How about you Sam??
Sam said:"I really need to go to the Toilet, i'm sorry.."
Teacher: That's better but still not nice to say the word Toilet..
Oh you Little Johnny?? Can you use your brain??
Little Johnny said:"Darling, May i please be excused for a moment??
I've got to shake hands with a very dear friend of mine, whom i hope
to introduce to you after dinner."
"TEACHER FAINTED!!!"
