Come to the Yip-Yip club to chat about Sesame Street's much loved martians/aliens Trade pictures, audio or video files of them, if you have any. Although they've been all but retired from the show, take some time out to remember these little dudes. They've even suddenly got a serious selection of merchandise (calendars, t-shirts, plushes), starred in Sesame Street Live: Out of this World, and have been parodied on Drawn Together.

The current group picture is available in our photos section.

To join, just answer the question of "What show are the Yip-Yip aliens from?"
