TV Quote from Community 01x21: Contemporary American Poultry

Pierce: Ay-bed, your social skills aren't exactly "streets ahead." Know what I mean?
Abed: I don't.
Jeff: You're not alone in this case. Pierce, stop trying to coin the phrase "streets ahead."
Pierce: Trying? Coined and minted! Been there, coined that! "Streets ahead" is verbal... wildfire!
Annie: Does it just mean "cool," or is it supposed to be like, "miles ahead"?
Pierce: If you have to ask, you're streets behind.
