We each tell the driver a joke
"We have a routine every time we get on a bus. We each tell the driver a joke.
He says:
'What happens if you run in front of a bus?'
'You get run down.'
Then I say:
'What happens if you run behind a bus?'
'You get exhausted.'
One time we made a lady laugh so hard that it sent the entire bus into a laughter meditation."
