Super Mario Bros. Speedrun in

"The most clutch gamer alive." It was supposed to be a joke but somehow this happened- the first 4:55 in Super Mario Bros. and probably the last second-barrier that will ever be broken in this game. When I say "My FIRST run" in this video, I mean my first run ever to get past 1-2 on that pace. The 9 in the top corner of the timer was to keep track of how many attempts I'd done once I started going for the pipe clip in 1-2, so this was my 9th run since I started attempting that trick and my first run that got it successfully.

I can't believe this happened, but I'm very proud of this accomplishment :)

Here is a list of specific frequently asked questions with answers and resources:

Q: How did you skip the flag coming down in 1-1, 4-1, and 8-3?

A: A very precise jump at the bottom of the flagpole makes the flag not come down. Someone by the name of Sockfolder figured out a somewhat consistent way for humans to do this. Watch this video for more information:    • flagpole glitch  

Q: Why did you not die when you touched the piranha plants?

A: This is an old game and a lot of the enemy hitboxes aren't in line with the enemy sprites. Look at this picture to see what i mean http://i.imgur.com/DpY0WaS.png

Q: How did you get inside the wall in 4-2? Why did the pipe take you to the warp zone? Aren't you supposed to climb the vine?

A: Very precise inputs make it possible to get inside the wall. This lets us change how close mario is to the right edge of the screen and tricks the game into sending you to the wrong place. I do a similar thing in the 3rd room of 8-4. For more info:    • How is this speedrun possible? Super ...  

Q: What did you do at the flagpole in 8-2?

A: This is similar to the glitch I did in the other levels to skip the flagpole, but even better. Look at this picture for details: http://i.imgur.com/DpY0WaS.png

Q: How did you jump off the pipe in 8-4?

A: By jumping at a very precise spot on the pipe Mario will actually stand inside of the pipe for 1/60th of a second, and if you press the jump button during this period of time you will jump. More info on this image: http://i.imgur.com/DpY0WaS.png

Q: How did you not die to bowser's hammers?

A: Sometimes you simply jump through a gap in the hammers, and sometimes you actually go right through a hammer. This is because the game can't always handle having all those hammers on screen at once, so some of them don't have hitboxes.
