Girl on Bike

Girl on Bike is an ad created by Vancouver-based fair Playland for their Fright Nights attraction, made in 2007.

The video shows a girl riding a bicycle through a fair on a sunny day. Similar to the K-fee commercials, it appears to be a normal video, and quiet music plays in the background. About 15 seconds into the video, a hooded person wearing a mask appears with a loud scream. The screen then turns black, and white text reading "Dare yourself" and "Double-dare your friends" appears shortly. Afterwards, the actual promotion for the fair appears with text that says "Scare your friends by clicking the button below".
