This nerd shows off how he's taught himself to memorize the gameplay of Super Mario Brothers on the original Nintendo Entertainment System (NES).

In case you think he's using a trick like using an unplugged controller while someone else plays or looking in a mirror or the video camera LCD, he talks about just practicing a little and describes textually how to accomplish what he demonstrates in the video:

"Level 1: Doo do do do do DOOT (jump, hit goomba). Run right, hit a pipe. Do a long button press jump over it, run right. Jump on top of the pipe, running start, jump to the next pipe, fall on the second goomba. Run right, jump on the pipe, inch right, press down. Jump right and run, then left, then right into the pipe. Wait for the music cue.. top of the pipe. Run left to get a running start, jump over the top. Jump to victory!

Level 2: do do do do do doot.. you're on the ground. Time it right, hit the mushroom box and land on the goomba . Jump up then left, collect the mushroom. Run right, hit the block. Three long jumps, hopefully land on the goomba near the coin box. Run right, jump, then jump again to hopefully get to the top row with the coins (safer way). If not, hope those koopas don't get you. Run to the right and break the three bricks, careful the enemies might get through if you're late. Jump up, then press right. Break two blocks, then jump left. Break one.. run! Count to 14 then long jump wildly. If you don't hear and bricks breaking, go left and into the warp zone. If you do hit a brick, go left for a second then right into the pipe. Mad dash to victory!"
