The first episode has Flynn referring to a damaged Grinder as a "Piece of scrap!", but with his accent it's hard to make out the 'S'.
Even the closed captions can't make out the 'S' and it reads "Piece of crap!"
Summer and Dillon are about to have their Last Kiss being trapped in a burning factory. They move in on each other, grip each other tight, and... the Whale Zord blows water all over the factory, leaving the two soaking wet.
Only by facing a vacuum cleaner monster could Ranger Red get away with the line: "Suck on this!"
Don't forget Ziggy teleporting into Dr K's chair with the Teen Genius getting a very... exhilarated face after she finds herself in his lap.
