In the morning, Johnny, Mary's little brother, gets up and has his breakfast.
As he is going out of the door to go to school, he asks his mom if Peter and Mary are up yet.
She replies: "No."
Johnny asks: "Do you know what I think?"
His mom replies: "I don't want to hear what you think! Just go to school."
Johnny comes home for lunch and asks his mom: "Are Peter and Mary up yet?"
She replies: "No."
Johnny says: "Do you know what I think?"
His mom replies: "Never mind what you think! Eat your lunch and go back to school."
After school, Johnny comes home and asks again: "Are Peter and Mary up yet?"
His mom says: "No."
He asks: "Do you know what I think?"
His mom replies: "Ok, now tell me what you think?"
He says: "Last night Peter came to my room for Vaseline and I think...I gave him instant adhesive!"
