Go find a busy street in a city somewhere. Hide in an alley nearby (preferably without a murder living in it). Grab a boombox/speakers/etc and play the TARDIS whooshing sound continuously. Wait for desperate Whovians to run into the alleyway. Laugh at the crushing looks of heartbreak on their faces when they see me giggling and twitching instead of the Doctor beckoning them into his TARDIS. @uljabubbles
