You've Got Time

If you’re interested in mischief you’ll never see play out, try the following prank on ne’er-do-wells.

Get some keys cut. Get some key chains you can write on. On each key/key chain, write a random address somewhere in your city. Scatter these about town.

Sit back, relax and assume some jackass will try to use the keys at the unrelated addresses printed on them. They expected easy entry, only to be foiled by your ruse.

Complicated? A bit. Pointless? Perhaps. Doable? Unlike any mischief involving teleportation, yes.
