Esbee sent me the link to the Annoy-a-tron so you can thank her if your ears are tortured any time in the near future. Here’s the description:

The Annoy-a-tron generates a short (but very annoying, hence the name)
beep every few minutes. Your unsuspecting target will have a hard time
‘timing’ the location of the sound because the beeps will vary in
intervals ranging from 2 to 8 minutes. The 2kHz sound is generically
annoying enough, but if you really really want to aggravate somebody,
select the 12 kHz sound. Trust us. The higher frequency and slight
‘electronic noise’ built into that soundbyte will make a full-grown
Admin wonder where his packets are.

Applications I’m considering for this ingenious device:

1. Next PTA meeting.
2. Car dealership show room, sales area.
3. Forsyth County Commissioners meeting, behind the commissioners’ table.  Set for loudest setting during the sectarian invocation.
4. Anywhere that teenagers gather en masse; they bug the hell out of me all the time so I think I’m due some payback.
5. Anywhere that pompous, self-important blowhards congregate en masse; see reasoning in item 5. (Yes I’m aware that this could be considered redundant to item 3).

Yes, yes, yes.  Much fun.
