wtf is a command

After a friend said "man wtf" in an IM, I thought it might be funny to type that into my shell and paste the output (never mind that it wouldn't actually be funny). I was expecting something like:

cozzy@localhost: man wtf
No manual entry for wtf

Instead, I was greeted with a man page for a program called wtf, apparently part of the bsdgames collection that I must have installed at some point. Go figure.

[cozzy@localhost ~]$ wtf is this
Gee... I don't know what this means...
