Euclid

Euclid was a Greek mathematician known for his works in geometry in The Elements. His works, however, are restricted primarily to plane geometry, and some of his postulates, including the last one, do not work on non-planar surfaces. However, his ideas in geometry have been well accepted for centuries.

Imagine that your barber’s name is Zeno and he is doing 1/2 off haircuts. Probably he would do a geometric haircut. This is hilarious.
