Funniest/Dumbest Movie Ever?

I recently watched The Three Amigos directed by John Landis and starring Chevy Chase, Steve Martin, and Martin Short as three "amigos." I watched it with a couple of friends, and it was probably the dumbest movie I have watched in a LONG time. There were so many moments that were absolutely ridiculous that I just had to laugh, like the "Singing Bush" scene (the clip below)

That was probably one of the dumbest and funniest scenes in the movie. The "magic chant" they have to say is absolutely hilarious in a really strange way. We had to pause the movie there and watch it over just because it was so ridiculous. There were many other scenes like this one (the dancing and singing in the bar while everyone thought they were cold blooded killers).

I have to say these two videos demonstrate the true nature of cowboys.....NOT! These completely contradict what is commonly accepted as a cowboy. It truly does what a parody is supposed to do: make fun of a certain genre. I found that this movie was pretty funny, but I would definitely not watch it again...

The Nightmare Before Christmas

I recently acquired the digitally remastered DVD collector's edition of Tim Burton's The Nightmare Before Christmas. It has always been one of my favorite movies, even though it is widely considered a kiddy movie. The basic plot of the movie is that Jack Skellington, who lives in Halloween Town, falls into a tree and ends up in Christmas Town. After exploring Christmas Town, he decides he wants to bring Christmas to Halloween Town. He tries and ends up failing, but it is thanks to Sally, the "woman" who loves him to fix things.
Even though I already own this movie on VHS, it is totally worth it to own the DVD version. First of all, my VHS player hardly works, and secondly, the quality of the sound and picture is greatly improved in the new remastered version. Plus, all of the bonus features in the set make it all more worth the while. If anyone was ever a fan of this movie, they should look into this collector's edition, especially if they don't own the original VHS copy. Learning all about how Tim Burton used stop motion and about the background information on the storyline and the characters really adds to the overall amazingness of this movie. And yes, it is truly amazing so it deserves "amazingness" to be made up for it.

*EDIT*
The music in this movie is also very cheesy, but that only makes it all the better. I never really managed to learn the songs, but i love them nonetheless. My favorite song is for sure the Oogie Boogie Song or the Halloween Town theme song... I can't decide... They're all so good.
