Button flies

Other than avoiding the horrendous "scrotum stuck in a zipper" possibility, there is not a single redeeming quality in these things.

Did someone sit around one day and say "hey you know what? I'm tired of being able to put on/take my pants off so easily. Also I wish it took longer for me to pee. Let's replace the zipper with lots of buttons!"? Whoever this person is, I hope they are rotting in Hell.
