LITTLE JOHNNY & VIAGRA

The Teacher asks kindergarten students what kind of medicines they know and what they are used for.

First pupil: 'Tylenol?'
Teacher: 'Very good! And what is it used for?'
Pupil: 'It is used for headaches.'

Second pupil: ''Nytol'
Teacher: 'Excellent. And what it is used for?'
Pupil: 'To help you sleep.'

Now it's Johnny's turn and he says: 'Viagra'
Teacher, slightly shocked: 'Johnny, What do you think is it used for?'
Johnny: 'It can be used for diarrhea.'
Teacher: 'Who told you this?'
Johnny: 'Nobody, but every evening my mother tells my father ..
'Take a Viagra, maybe that little shit will get harder.'
