If it's a elevator in your own building, build the front of a Chinese take-out restaurant in the doorway of the elevator at night. Then when people call the elevator in the morning and it opens up in front of them, lean out dressed like a cook and ask them in a Chinese accent what they would like to order.
Ah man, I saw a list of these at the Dilbert website years ago. Man, can't remember many...
For uncomfortable elevator rides:
--Talking to yourself / Strike up a conversation with someone who isn't there.
--Pick nose in public.
--Hit on people.
--Start singing to yourself. The louder the better. (For example: "I AM IRON MAN!!!"😉
--For kids: "Hey everyone I've got a loose tooth! Look it's wiggling and bleeding!"
--After everyone's just got in solicite them to join your religion.
--If they're going up, say: "Have you ever considered all the benefits down has to offer?"
--Remember that scene from Spidey 2 where he's in costume in the elevator? Something like that, maybe?
-- Elaborating on that theme other ways to make so-called normal people uncomfortable dress in...
...a white shirt stained with ketchup or red paint.
... a turban
...like Rambo
...like Neo or Trinity better yet have 2 people do the act and bring a large heavy bag with a digital read-out.
...and rememeber "there is no spoon." 😛
Hahaha, good ones above!
How about dressing up real slick, put on a name tag and pretend to be a real estate salesman. Then try to sell the people the elevator it self!
'And here we have the multifunctional control panel, no elevator can do without there days. Let me demonstrate, it can go up as well as down, and comes with an emergency brake system, gotta love it! (push all buttons).' 'I know what you're thinking, how am I ever gonna afford a elevator like this? Well m'am, have a look at our special long term payment option! Am I hearing a yes?'
