This takes patience and a good look out, but pierce the top of someone's opened soda just below the opening. I've only seen it once, but it was hilarious.
I'm a mechanic and we've had some pretty lengthy prank wars. Opened someone's tool box and zip tied all their tools in tight bundles, including the cutting pliers. Empty the box and replace the tools with similar weight. And best of all, cut the threads off of a grease fitting and glue it to the top of their tool cabinet. Proceed to dribble grease on the fitting and the edges of the drawers. OR you could actually install it.
I have plenty more I'll save for later.
