Girl on Bike is a YouTube video. It shows a fun fair on a sunny day, and shows a girl riding a bike, which is obviously an inspiration from the K-fee commercials. When the camera passes on a close-up shot of a ride from the fair, a hooded person with a scary mask pops up with a scream, before the video cuts to a black screen. It ends with a message from the beginning and asks you to double dare your friends.
NOTE: The following video contains a screamer.
