The material has been written, produced and directed by Joly, best known for Channel 4's 'Trigger Happy TV', to celebrate the launch of Cadbury Creme Egg Twisted.
The series of seven online films, called "Twisted TV", are designed to build on the twisted sense of humour and "wicked personality" of Creme Egg Twisted, which was established in TV ads last month.
Some of the unsuspecting victims of pranks on "Twisted TV" include silver witches, burrito sellers and a traffic warden who is squirted with goo.
The clips will appear on YouTube from today and social networking site Bragster, where users will be able to enter a competition to win a Nintendo Wii by entering their own "Twisted TV" footage.
Bragster is an online community where the public can challenge each other, claim victory and brag about it.
New footage will be added every couple of days to Twisted TV to encourage fans to come back.
Joly said: "I'd never thought of being a chocolate bar in 'Trigger Happy' so this is a first. And it's always good to keep my hand in at annoying traffic wardens."
