a catchphrase said by "that guy" in Futurama Season 4 Episode 9 (Futurestock) emphasizing his 80's style. Back in the 80's "Awesome" and "to the max!" were hackneyed quips that people would spout to sound cool. Nowadays, people usually say it for camp value... especially since even in the 80's it was slightly tacky...
FRY: (whispers to That Guy) Hey, buddy... I'm from the same time as you. Remember that song, Safety Dance?
THAT GUY: Sure do! We can dance!
(starts humming 'The Safety Dance' and Fry follows)
FRY: Y'know, that dance wasn't as safe as they said it was.
THAT GUY: I tell you; Two go-go 80's Reaganauts like us... we could rule this world!
FRY: No question!
THAT GUY: If only someone would give us a shot.
FRY: They're scared of our raw power. Oh, but if you want a job, I could beg everyone at the company where I work.
the term was invented by Bart Simpson in the Episode "She of Little Faith" (Episode 275 - DABF02, Season 13) when homer was buliding a model rocket, Milhouse commented that he never knew that Homer was so interested in Science, but since Homer hates science (and nerds), Bart said Milhouse actually said "pie pants"... to which homer replied "mmmmm pie pants".... later he says "the word un-blowuppable is thrown around alot these days..." freaking hilarious!
mmmmm pie pants - a great food, and for simpsons geeks, another word for science
