the perfect noun/adjective/verb substitute

So I borrowed The Smurfs on DVD from the library so Emily understands what the little blue creatures on our refrigerator magnets are... and realized just how much they use 'smurf' as a word substitute- good, bad, and in between! My favorites are:

"What the smurf is going on in here?!"
"Quit smurfing around!"
"Smurftastic!"
