["I was surprised a co-worker of mine just got a raise! He doesn't do much work at all...", 'Uh ohhh.  When is it gonna be your turn?!', "That's what I am wondering! Just a bit miffed about it. I think I do twice the work."]
Wonder if it would help if I call your boss and tell him to give you a raise?
A co-worker just got a big raise and he does about only half the work I do.
