Little Johnny-- love this one 

A teacher asked her class how many of them were  Bernie
Sanders fans.

Not really knowing what a Bernie Sanders fan is, but wanting to
be liked by the teacher, all the kids raised their
hands except for Little Johnny.

The teacher asked Little Johnny why he has decided to be
different...again.

Little Johnny said, 'Because I'm not a Bernie Sanders fan.'

The teacher asked, 'Why aren't you a Bernie Sanders fan?'

Johnny said, 'Because I'm a Conservative.'

The teacher asked him why he's a Conservative.
Little Johnny answered, 'Well, my Mum's
a Conservative and my Dad's a Conservative, so I'm a
Conservative.'

Annoyed by this answer, the teacher asked,
'If your Mum was a Moron and your Dad was an idiot, what would that make you?'

Little Johnny replied,
'A  Bernie Sanders fan.'
