A biologist, a physicist and a mathematician were sitting in a street cafe watching the crowd. Across the street they saw a man and a woman entering a building. Ten minutes they reappeared together with a third person.

- They have multiplied, said the biologist.

- Oh no, an error in measurement, the physicist sighed.

- If exactly one person enters the building now, it will be empty again, the mathematician concluded.

The world revolves around me. Deal with it.

Thanks. I like this joke because biology and mathematics aren't necessarily used simultaneously in a joke like this.
