Bubble in the Bathtub

A new lady teacher came to teach 8th standard students. As it was the first day,
She gave her intro, and asked all the students to introduce themselves with name and hobby.

She said, " Let's start with the boys first."

Boys start giving their intro...

First boy: " My name is John, and my hobby is to see bubble in the bathtub."

Teacher was confused to listen but said, " Interesting. Well, Ok. In fact we must be honest in telling the hobby. And after all there is essentially a child in each of us. So it's ok John. Yes next."

Second boy: " Myself Peter and my hobby is to see bubble in the bathtub."

Teacher now got surprised and said, " Good. I like the spirit of supporting a friend. Ok next."

Third boy: " I'm Smith and my hobby is to see bubble in the bathtub."

Teacher: " Guys are you joking or what? Please be sincere. Ok next."

This continues, and the last boy stands up " I'm Harry and my hobby is to see bubble in the bathtub ."

Exhausted, the teacher said, " I don't think I will be able to teach un-grown boys for long. Anyway, now the girls please."

First girl: " I'm Julie and my hobby is to see birds."

Teacher: " Good. At last I got something different. Ok next."

Second girl: " I'm Ruby and I like to collect perfumes."

Teacher " Now it's like educated grown up girls. Ok next. You sweet girl , Yes you..." the Most beautiful girl of the class :

" Mam, my name is Bubble, and my hobby is to take a looooong bath in the bathtub."

A girl says to her boyfriend, "One kiss and I'll be yours forever"
The guy says "thanks for the warning"
