Little Johnny comes to mommy and says:
“Mommy, I want a dog.”
“No way!” says the mother.
“Dogs are dirty, messy, leave hair everywhere and smell!”
Johnny says again: “I want a dog!”
Mother: “I already said there won’t be any dog here. Wish anything else.”
Little Johnny thinks for a minute and then says:
“Fair enough, mom. I wanna play a mother and a father.”
Mother, thinking it kinda sounds like incest, thinks about it for a minute and then says:
“OK. One cannot hurt. We can do that, Johnny.”
Little Johnny looks at her and continues:
“Go get a bath, put on some nice clothes and wait for me in your bedroom.”
Mom does as Johnny wants and patiently waits for her son.
