It was "ludicrous speed" followed by the realization that "They've gone plaid".
Spaceballs was pretty weak with alot of forced gags. Some good stuff in there (mostly from Rick Moranis), but overall pretty lame.
Mel Brooks and Monty Python movies are completely different animals. I can't say I like YF or Blazing Saddles any less than Meaning of Life or The Holy Grail. Some of Monty Python's humor is a bit more dry, but some of Mel Brooks stuff is suprisingly original.
I have all their stuff listed above (except meaning of life that was pulled from shelves for some reason) and will get more from both of Mel and Monty.
