Head Bobbing In Live Action

You know how in old 3D video games, when the characters talk, instead of moving their mouths, they would simply move their heads up and down? Just to show you, here's a cutscene from Tomb Raider 3.

Do you know of any video game parody videos where actors do the head bobbing thing in live action?

That's weird.  One taking game I played was Q*bert.  He would have a word balloon appear above him when he spoke.

Red vs Blue uses this as a speaking method, which they lampoon at one point. RvB is kinda shit though.
