There was this statistics student who, when driving his car, would
always accelerate hard before coming to any junction, whizz straight
over it, then slow down again once he'd got over it.

One day, he took a
passenger, who was understandably unnerved by his driving style, and
asked him why he went so fast over junctions.

The statistics student
replied, "Well, statistically speaking, you are far more likely to
have an accident at a junction, so I just make sure that I spend less
time there."
