Alternate endings

I was thinking about different structures that we could do. One is called "Alternate Endings". We've all seen or done similar structures like this.

We get a suggestion from the audience of a well-known movie or book. Then, say to the crowd "Now, we all know how this REALLY ended... give me an alternate ending."

We could have a bunch of suggestions (decided by us ahead of time) in a hat that an audience member could draw from or just fly blind off of a suggestion from the crowd. Three or more performers would do the new scene. Could be lots of fun!
