I just remembered, didn't they do this? I watched the series on passing a few months back and remember them doing something called the Backwards Chicken Dance with the same moves.

Oh maybe

I thought theirs was more with the leg thing

They do it in this clip

I think the BCD could be the dance craze of the summer.

It's gone half midnight and there are still people out in the streets doing it here.

That's their leg thing, but I remember them doing a flappy thing behind their backs and cocking their heads like chickens on Live Feed. Maybe that was one time, but I remember it on Live Feed.
