Another proactive spider-web-air-karate-guy here.
This may be TMI, but somewhere along the line I taught myself not to pull at my … er … “bathing-suit area” when things needed to be readjusted but instead to sort of stomp the ground while doing what feels like a subtle hip rock. It usually does the job, but I’ve recently learned from Mrs. ToKnow that to someone who doesn’t know what I’m doing it looks like the potty dance.
I remember a long time ago ( 1970s ) that advice was given as the best way to get into a car without twisting the spine. It does make sense, especially when getting into/out of lower slung sport coupes. The thing is though, many seats are bolstered, some heavily, and make the way that you describe more awkward.
I once vacuumed my front porch, front door and the outside walls in the surrounding area.
Why, you ask?
[spoiler]Spiders. Baby spiders. Hundreds of them. Maybe thousands.
They would hatch underneath the porch every spring and go roaming all over the place. One time they wandered in through a crack by the kitchen window. Had to vacuum them off the walls and ceiling. I don’t think they were the psycho killer Australian kind, I just didn’t want them dropping down on top of me while I was sleeping or anything.[/spoiler]
It was kind of like this.
My old apartment was in a complex of small 2 story apartment buildings, so I would park in the lot and walk past a few of the buildings to get to mine. If I was coming home in the evening, I’d walk very loudly, maybe not quite stomping my feet, but definitely making noise.
My future wife, during one of our early dates, asked me just what the hell was up with all the stomping. Well, our complex had resident skunks, and the very last thing I wanted to do was surprise one by walking quietly around a corner. So, I figured I’d give them a warning.
I do this with my computer bag. If I take my computer home from the office, I drop my keys into the bag, so I can’t leave for the office without bringing the bag with me. Only took me two trips without my computer to learn that one.
About 5 years ago I reluctantly removed my plumb tree. I have regretted it ever since. Every morning I used to go outside and pee on the tree while holding my coffee and have a few minutes conversation with the tree. A stranger might think I was delusional but for me it was just a day starter and I guess my form of meditation. I replaced it with a bonsai in progress that I kept on my outdoor coffee table but last year it died. I need to start a new one. I miss our conversations.
I’ve got to know: What did you do with a vacuum full of spiders?
Don’t pee on the bonsai, though. Not enough soil to handle the urea/nitrogen load.

We’ll pee on the bonsai
We’ll laugh every day
We’ll pee on the bonsai
Then I’ll be on my way.
Emptied it, of course. There was so much dust in there already that they all choked and died. 
I read this too quickly initially and couldn’t figure out how you didn’t see a moose (or, for that matter, how it got a boot on).
I call that “the ADD grope”. I’ve left my phone, wallet, keys, etc. behind many a time. I’ve learned to run through a checklist before I leave any public space where I might have had them out. I also take a long look back at any subway seat, restaurant booth, or such, where I’ve just been sitting.
I’m stealing the ADD grope name. I do the same thing.
Two things I do that co-workers have actually asked me about.
First, when I go in the break room, I always walk over to the microwave and press the “clear” button (unless it’s running.) The reason is because a lot of stuff I do on my phone at break and lunch obscures the clock and it’s easier to look at the microwave then close out/minimize the app. The problem is that many of my co-workers take stuff out before it ends, leaving a scrolling message instead of the time.
The second is my phone’s lock screen. In a very large font, it says “ICE - NAME (123)456-7890.” It’s my wife’s name and number. It seems a lot of people still don’t know about ICE. It stands for In Case of Emergency with name and contact number, so if you’re in an emergency, anybody can know who to contact.
I have many other quirks that don’t make sense and that I can’t even explain.
Ever since I was a kid, I’ve been told I look before I bite into food. I unconsciously, but seemingly deliberately examine the food, and pick an exact spot to bite.
I don’t knowingly do it, but since it’s been pointed out to me, I have caught myself doing it.
It’s almost like working backwards on some demented puzzle.
When I’m walking down stairs, I hit the step with the back of my heel before placing my foot on the next lower tread.
I don’t think I’ve ever fallen down stairs, but I’m still afraid of overshooting and this helps me feel like I’m going to put my foot squarely on the next step.
