Here's the new sarcastic phrase I would like to popularize: "You're a regular Smarty Jones, aren't you?" Please use it from now on whenever anyone pretentiously shows off their knowledge in your presence. (Yes, even if I do that.)

Original comments...

Jeremy: Why is Smarty Jones better than Smarty Pants?

Jim: Because Smarty Pants is not a Kentucky Derby-winning horse.

Jeremy: So your proposed sarcastic phrase is something I should say to a slow person?
