i saw a video at school, it was like a short film type of video. it was freaking hilarious.

i remember there were two guys, alex and derek, and each scene was derek popping out of nowhere and being like "hey alex, what're you doing???" and then alex is like "NOT NOW DEREK!!!!"

but i can't find it for the life of me. has anyone seen this? do you know what it's called or what the person's username is that has it?
