P is for P's and Q is for Q's, but no one is really sure what P or Q stands for. I think it makes a great way to catch up on two weeks worth of ABC Wednesdays.
Whenever I have heard the expression, "Mind your P's and Q's" it's always appeared to be a reference to having good behavior, kind of like saying, "Mind your manners." At any rate, it's a warning to pay attention to what you're supposed to be doing and whether or not it has anything to do with a P or Q is anybody's guess.
