choose a location, some characters and a situation and write - then
perform - a brief sketch.
From one group of (presumably) physics enthusiasts among my English students.
------------------------------------------
Einstein and Newton are playing together in Heaven.
Einstein: Do you want to play hide and seek.
Newton: OK
Einstein: I'll close my eyes and you hide.
Newton: OK
<Einstein closes eyes>
<Newton draws a one metre square on the ground and stands in the middle of it.>
Einstein: Are you ready?
Newton: Yes, I'm ready.
<Einstein opens eyes>
Einstein: Hello Pascal. Where did Newton go?

It took me few seconds to figure out and I have a physics A-level
(admittedly from a long time ago.)
