Because I want to make a movie of us all jumping over the edge of a map at the same time. I'd jump last to film the rest of you "sky diving". And I want to try it on a few maps with a full room for a few different effects.
I can help make up the numbers if needed - that's one thing I'm good at.
You could probably try some variations on this theme - line everyone up like bowling pins on the edge of a cliff, then use the hammer to see how many you could knock off.
