Part of the fun of doing improv is being able to do anything. Like Neo in The Matrix, you can fly, stop bullets, or even hook up with The Woman in the Red Dress; things mere mortals can only dream of.

Sometimes we add crazy elements to a scene, thinking we’re making it funnier. But what often happens when characters go to Mars is so does believability.

The audience needs a reason to believe.

I once saw Jason DeRosse, Rob Norman, and Adam Cawley ask for a location that would fit on the stage. Someone yelled out “Shoe!”

The guys paused and looked at each other, then played 25 minutes as three roommates trapped in a stiletto.

The setting was absurd, but their reactions and their relationship to each other were grounded in truthfulness. And nothing is funnier than truth in comedy.
