so; you're browsing through tumblr, and see a variety of posts. kanye, memes, youtubers... and one (i mean two but one sounds better) happened to be danisnotonfire and amazingphil. you've heard of "dan and phil" before, but you've never really bothered to check them out. the curiosity is killing you! you give into the urge, and quickly go on youtube and search for dan and phil. you were expecting one channel, but there's these guys called amazingphil and danisnotonfire. ugh. weren't they meant to be popular? where are dan and phil's channels? then it occurred to you. these are dan and phil. sigh.
so you watch a few videos, and four hours later you're still watching how to speak internet.
congratulations, you have found out about phan!
