You'll need some sort of catchphrase/catch-action.
I'm thinking along the lines of a Bill'n'Ted style air guitar solo, or was that Wayne'n'Garth?

Or maybe you can do a robot dance, where someone unexpected happens, like you press a button behind your ear, and some skates appear from the bottom of your boots, and then you do some sort of figure-skate manovour, and then you get out your air-hockey-stick, and whack an air-puck, but it makes a real-life ding sound.

I'm just going to do what I usually do and get an embarrassingly timed errection
"Ooh god, Am at a funeral and got a right solid Broom-On, AAAAH GAWD!"

"Ooh god, Am talking to me nan and I've got a right branch poking at her, AAAHH GAWD!"
