John Cleese(who was in Holy Grail) had a show called Fawlty Towers that was friggin' hilarious. If you're a fan of that kind of humor, it's worth checking out at least once.
If you guys want to see something John Cleese did that was actually funny, check out A Fish Called Wanda. (but really most of the humor comes from Kevin Kline)
Fierce Creatures was sort of like the "sequel" (more like a reforming of the cast to make another movie) and was also very funny, but not quite as good.
lmao, *sigh* well, I gotta go see if I can find this movie anywhere tomorrow; I haven't seen it in years. Might see if I can find the Holy Grail while I'm at it. I need them both for my collection anyway. lol
The scene with Caesar and the joke names, "It's a joke name sir. You know like Bigus Dickus? I have a very good fwend in wome named Bigus Dickus! What's so funny about that"?
From the other I'd have to go with the three questions scene. "oh that's easy let me try. What is your favorite color? -- Red... err wait blue -- arrrrrrgggghhh (as being cast off of cliff for answering incorrectly)".
