Someone posted this on a chan forum, and I nestalgia'd hard. So here is an Ode to SMB 3 thread (and old games in general):

Back on topic though; I popped in the game in my new NES and pressed Start. I started at World 1, of course, and began playing. During this, I got used to the controls, map, and all that jazz. After all, it IS supposed to be kinda like a tutorial level. So I had advanced to World 2, "Desert Land" and I was moving along rather smoothly. In the back of my mind, I knew that at some point the levels would start to get more difficult. I soon noticed a tile, one unlike the other tiles (Toad houses, numbered tiles, etc). It appeared to be some cross-hybrid of flowing diarrhea and sand, which caught my attention. I navigated my way to the tile, and hit the A button and was warped to what appeared to be a normal level; there even was a happy sunshine in the top left corner! As I side-scrolled my way through the level, the fucking sun decided to go apeshit and sodomize me repeatedly until I finally broke down in tears, throwing my controller at the ground screaming for my mom. That fucking bastard.

And no, this is not copy pasta.
This was actually posted in a baaw thread, which makes it more epic, but god I miss playing that game for the first time. :(
