--People (mostly young men) who wear stocking caps all the time. I mean, c'mon, the heat index is already 88 and it's not even 10:15 am (central time) and you have this thing on your head. The cap must be completely disgusting.
--People who voted for Dubya TWICE. Jeezus, fool me once shame on you, fool me twice, well you can't get fooled again. Or can you?
--People on the Iowa campus who smoke right in front of no-smoking signs. I generally have a sudden, uncontrollable urge to pass gas when I walk past them.
--People who always have to "one-up" you, no matter if it's good or bad. They're the types who always have the "worst case" of whatever ailment is going around, or their work day was "worse" than yours...
--Colorado potato beetles. They decimated my potato crop this year. They were the worst in my garden, I just know it!
--Asian beetles, mosquitos, gnats. They just suck, period!
--People who think they are singing to themselves, but sing loud enough for you to hear. They deserve to be punched twice if they don't know the words to the song.
--Loud motorcycles. I have an uncontrollable urge to cut them off in traffic, if for no other reason than to keep them behind me so I don't have to hear their stupid motorcycles. People with loud motorcycles deserve to be punched as well.
--Bicyclists who don't announce they are passing you while walking on a trail. It's just common courtesy to do so. I'm seriously thinking about getting an air horn and blow it whenever someone passes without saying something like "passing on your left;" and if they ask why I did that I'll just say "I'm announcing that you just passed me on my left."
I know I have a lot more pet peeves, but that's a start.
--My pager.
