they are used for.

Teacher: 'Very good! And what is it used for?'
Pupil: 'It is used for headaches'
Second pupil: 'Nytol Teacher'
Teacher: 'Excellent. And what it is used for?'

Now it is 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'
