Screw off the vent cap of a tire, find a really small piece of gravel, put it in the lid, screw it back on ever so slightly, so that you hear air leaving the vent.

Probably key the boot as I squeeze past

chainsaw? not what I'd do, but it is what i'd be picturing

Have my wife wheel me over to where the license plate # is in view and post that bad boy to social media with a sympathetic title like "we had to take a huge detour because we couldn't get my wheelchair around this truck", grab some popcorn and watch as people form a digital witch hunt. Then call the police to have it towed.

Call a tow truck company and get the spotter's fee reward.

Is it parked like that regularly and overnight? If so, well, you can buy a knockoff battery powered Makita angle grinder off Aliexpress for very little money and it's very useful to own one anyway, especially if you also own an old car where bolts keep rusting shut so bad it's easier to cut things off.

In this instance, I'd recommend doing just the tow hitch. If you get caught there's less damages to pay, it creates enough space for most people to pass, and the owner of the truck will probably get the message. Plus it would take way too long to cut off any part of the bed

Take a picture of it and post it on social media for likes.

Call the city line and report illegal parking. They will at least get a nice ticket, and if you're lucky, they'll get towed :)

Fantasize about violence. Probably no real action other than banging into it when walking on the sidewalk.

How thoughtful, they've brought me a canvas for my keys.

Come back and search for a bat 🤑

Deflate the tires and use the truck bed as a trash can and/or porta potty.

Ball style tow hitches are usually removable by a very visible cotter pin! Free ball hitch!

The icing on the cake is having the hitch ball mounted when they've probably never towed anything in their life. Make problems, and destroy some people's knees at the same time.

I'd just complain about it and tale a picture. I don't fuck with other people's stuff.

Parkour :D

I'd take a sharp object and write the following notes on their door:

"Hi there, I was going to write this note on paper but I didn't have any on me so I figured this was the next best option. Anywho, just wanted to let you know that your car is parked on the sidewalk and blocking people from walking safely away from the street. I know it was probably an accident, so no biggie! Just wanted to let you know for next time so you can be mindful of others. Have a great day, friend!"

Bonus points - If I have them on me, bb pellets and super glue. You take the air stem cap off their tire valve, put in a drop of super glue and then a bb pellet. Screw it back on. It will slowly leak air out overtime, and the driver will go crazy trying to figure out why that tire is slowly letter air out.

I hate these fuckers. This happens a lot in my home town. I was young i just cursed the fuckers and kept going. Nowadays i would deflate the tire.
