There was an inflatable boy, who went to an inflatable school.

he was smoking behind the school shed when the inflatable teacher caught him.

"Right" he said,  "you're coming with me" and dragged him backed to the classroom.

The inflatable boy pulled out a knife and stabbed the inflatable teacher, swoooosh (sound of air coming out) went the inflatable teacher.

He ran out the school gate and stabbed the inflatable school, swooosh went the inflatable school.

The inflatable boy ran home, where his inflatable parents said "what are you doing here? You have been in trouble at school, haven't you?"

The inflatable boy stabbed his parents, swooosh they went.

The police arrived to take him away, but he stabbed himself.

They rushed the inflatable boy to hospital, where they stitched him up and left him overnight.

The police came back the next day and the inflatable boy asked what happened?

The Police said, " you've let your teacher down, you've let the school down, you've let your parents down

And most all, You've let yourself down"

Geez, you are a hard crowd to get a laugh out of............If this didn't make you smile, check your pulse.

He also had an inflated opinion of himself

He went down on himself
