"Yogurt!" "Yogurt the Magnificient!" "Yogurt the Wise!" "Yogurt the All-Powerful!" "Nonono, it's just plain Yogurt." "START COMBING THE DESERT!" (crew takes out gigantic combs) "It's a 'Y'!" "YOGURT! Awwww, I HATE Yogurt! Even with strawberries!!!" But my all time favorite: "Moichandising! Spaceballs the DOLL! Spaceballs the Tee-Shirt! SPACEBALLS DA FLAME THROWER! Da kiddies love it!"
Oh, and I forgot one: "We're having trouble with the radar, sir! We've lost the Bleeps, the Cheeps, and the Creeps!" "The what?" "The what?" "And the what?" (makes noises) "The radar sir, it appears to be... JAMMED!" "Raspberry! Only ONE man would DARE give ME the Raspberry!"
That is one of my fav. as well, but for a different reason. The first times i saw the movie it was the italian version, and obviously the pun makes absolutely no sense. When i realized it, by thinking of it in english and doing the connections in my mind, i was SO satisfied...
"Stop! Who would cross the Bridge of Death must me answer these questions three, ere the other side he see." Grrr, Imrahil
We all know that if we have to define Spaceballs with a single sentence, that would be LUDICROUS SPEED!!!
