Boys will always remain boys

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, Lets 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. Infact, we must be honest in telling the hobby. And after all there is essentially a child in each of us. So its 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: Im 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 Im Harry and my hobby is to see bubble in the bathtub.

Exhausted, the teacher said, I dont think I will be able to teach un-grown boys for long.
Anyway, now the girls please.

First girl: Im Julie and my hobby is to see birds.

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

Second girl: Im Ruby and I like to collect perfumes.
