An algebraist, a statistician, a combinatorics major and a geometer walk into a bar.
The algebraist orders an obscure drink and leaves.
The statistician orders a drink that approximately suits his taste and leaves.
The geometer orders exactly the volume of his intended drink and stays over.
The combinatorics major orders his drinks, the geometer turns to him and asks him what he needs all these drinks for. He replies "I don't." and proceeds to fucking die.
