You can get the red Muppet on the end to eat his green long necked neighbor.
We were at the Chicago Museum of Science and Industry last winter and saw an exhibit on Jim Henson. Somewhere in the exhibit there was a clip where Henson said if they couldnt think of an ending for a skit, they would either blow something up, or someone would get eaten. I think of that now whenever I watch the Muppet show on DVD.
