Jimmy "MrBeast" Donaldson is an American YouTube commentator who currently resides in North Carolina. The channel is mainly run by Jimmy (himself) and his roommate Chris. His series, "Worst Intros", is arguably the reason his channel has gained popularity. There are about 60+ episodes of the series, and is still continuing. He also makes other series, for example, there is an opposite of "Worst Intros" which is "Best Intros" (which is not very different, as rather than inslting these intros, he praises them for their bad qualities). He also makes "Worst YouTube Channels Ever," etc. His channel had a spike in which he gained much fame and popularity by counting to 100k, which is estimated to continue.
The series is made of 60+ videos and is arguably the biggest reason he is popular on YouTube. In these videos, MrBeast rants on horrible intros. Throughout the series, he repeats the same jokes involving bleach, leaving a child home alone with a phone and explosions (which he claims can be used to cure brain cells of cancer). Most of the intros were recorded on smartphones, with the YouTubers dancing in front of the camera with music in the background, holding a sign that says their usernames (generally paper). To add even more insult to injury, you usually could not read what the sign says. He occasionally also stumbled upon troll intros made soley to become a part of his series
MrBeast is also known by hating Minecraft, a Swedish game developed by Mojang. He made a two-episode series of it, and was completely finished playing the game for good when his house got blown up by a creeper, the most famous antagonist in the game. Due to that incident, he removed the game from his computer. Ironically, Jimmy has started off playing this game on his YouTube channel.
MrBeast has 800,000 subscribers currently. Such has caused his fans to do some strange things in the name of him, such as run down their local street screaming his name.
