There was a video I saw posted to some humor subreddit, titled "GTA episode 7" (can't remember the actual number). It was a video simply of someone taking a video camera to their mailbox, reaching in and grabbing the mail which had ants all over it. The guy ran away yelling and the screen changed into something like the GTA V death screen, and it said "ANTS: there were ants." The channel's profile picture was a cactus with eyes or something very similar.

He had another video that was like an hour and a half of AFV audio in the game audiosurf.

I tried everything I could think of; I googled every name I could think this channel might be, every variation of "GTA V ants video", searched the subreddit I remember it being in, and surprisingly even searching for variations of "AFV audiosurf" doesn't return anything.

I remember his channel was pretty popular, and I was just hoping someone here might know who I'm talking about because it's just been driving me up a wall not being able to find this guy. It was bugging me so much that I went and found a subreddit I could actually ask these kind of questions!

Much appreciated for reading all this!
