Can you major in Plumbing?

I have come to a realization today......I am not a plumber. Nor do I ever have any intent or interest in becoming one. I came to this conclusion this morning after the toilet started making noises and deciding that it did not want to flush. I think I got it to work again, but that still does not mean that I will be taking up that trade any time soon. It is to nasty and disgusting for my tastes.
