Dinner Party Revenge

It's a shame people don't throw dinner parties much anymore, but this may be the reason the custom has fallen by the wayside. This guy has a diabolical plan to cause minor annoyances for his host for years to come! Plot twist: he shouldn't have bothered going to the trouble, because these things all occur naturally. I haven't thrown any dinner parties for years and I am still vexed by mysterious objects that appear in the most obscure places. But if it makes him feel better about putting up with his nemesis at work, then more power to him. It's another nonsensical yet amusing anecdote from Chris Hallbeck.  In the comments, we got a bonus real-life story about long-term revenge that you can read at Laughosaurus.
