Might I suggest leaving out a bag of popcorn that may or may not be sprinkled with Jalapeno powder?
Or maybe the classic Annoy-a-tron hidden in an enticing trinket?
(The classic random beep is priceless. I will forever remember DH's attempt at finding the source of the beep, and so will he.
Reminds me, I should go tell him how happy I am to have him as my life partner...)
Hahaha back in 2008 I bought an annoy-a-tron. I had a super annoying roommate at the time, and I hid it in his disgusting closet, then forgot about it.
One day, months later, he comes in my room completely satisfied.. He says, “for months I’ve had this stupid beeping in my room. It would come at different volumes, pitches, and intervals, and I could never find what it was, until I found THIS today,” and he pulls out the annoy a tron I put in his room haha.. He had no idea, nor ever suspected me..
Great times.
