The classic mishearing gag!It's one of my favorites!
I usually do this:
Are you married? (Kid: Nooooooooo )
Ooookkkkk!And how many kids do you have? (KiD: Noneeeeee )
Twenty one?????WOW!!!Twenty one kids in that age?How long have you been married??? kid: I don't have KIDS!!!!
Ok.I understand.You don't have children but ,surely,you have grandchildren!Are you a grandpaaaaaaaaa at that age???Oh my god!You don't even have grey hair!
Most of the times I get a great reaction so I continue to ask silly questions.
Also,sometimes I yell at them with my funny voice:
Ok, you,smart kids!!!
Who's gonna be the first that 'll come up here, stand next to me aaaaaaaaaand...( before I end the sentence, all hands are raised up,cause they think that I need a magic assistant.Then I continue... ) anddddddd PUT his trousers off!!! Or if I don't want things to be so "spicy"... andddddddd knock his head with my huge hammer( if I say it right in English - sorry )
They laugh all together and then I say that I need a magic assistant:
Wow!All hands raised!
But I need the best one!!!
Who's the quickest? KIDS:Meeeeeeeeeeeeeeeeeeeeeeeeeee
Who's the smartest? KIDS:Meeeeeeeeeeeeeeeeeeeeeeeeeee
Who's the best student? KIDS:Meeeeeeeeeeeeeeeeeeeeeeeeeee
Who's the strengthest? KIDS:Meeeeeeeeeeeeeeeeeeeeeeeeeee
and kids reply MEEEEEEEEEEE with a loud voice in every question,so suddenly I say
Who's the silliest??? KIDS: ( some of them answer MEEEEEEEEEE as they did in the previous questions and all of them lol )
I love these jokes!
They are easy and can really warm up the audience,not only kids.Usually parents laugh too.
