That movie quote meme

[bunny_m]

Well, over the past week or so I've seen this show up on just-about every lj that is on my friendslist. I've tried it a couple of times, proving that it's, at best, semi-random about which quote it supplies. So, being somewhat bored at work today, I sat there refreshing the page to see what 'good' quotes I could find. I was a rather undecided as to what the best one was out of an excellent field, including:

"Bunny M! Why'd it have to be Bunny M?" Raiders of the Lost Ark (Snakes);
"Lions and tigers and Bunny M, oh my!" The Wizard of Oz (bears);
"I'll be Bunny M" The Terminator (back);
"You know the difference between you and me? I make Bunny M look good." Men in Black (this);
"We're on a mission from Bunny M." The Blues Brothers (God);
"But why is the Bunny M gone?" Pirates of the Caribbean: The Curse of the Black Pearl (rum);
"Play it, Sam. Play 'As Bunny M Goes By'." Casablanca (Time);
"Round up the usual Bunny M" Casablanca (suspects);
"Oh, what sad times are these when passing ruffians can say 'Bunny M' at will to old ladies." Monty Python and the Holy Grail (Ni!) (A close second, I think.);

But then I rolled the perfect movie quote:

I defy you! Come and kneel before Bunny M!

Which movie was this quote from?
