US fast food giant Burger King began running a series of ad campaigns in 2004 to promote one of the items on their menu: the TenderCrisp chicken sandwich.

The campaign included a website — www.subservientchicken.com — with what appeared to be a webcam trained on a person dressed up as a chicken. Visitors to the website can type in any command in a text field and the "subservient chicken" then responds to it — often in unexpected ways.

It proved to be so successful that the website is still going strong four years later.

Normal commands like "sit", "laugh" and "fly" results in the appropriate actions, while any command it deems to be offensive will see the "chicken" walk up to the screen and shake its finger.

The idea of course is to experiment with different things, but here are some suggestions to get you going: begone, moonwalk, headbutt, fight, hide, do the YMCA, handstand.

Just for fun, see what he does with "eat Mcdonalds". And when you type "Crispin" the creators of the video will make an appearance!
