I used to carry a universal TV remote control with me. It’s simply staggering how often it was useful.

“YOU DRIVE VERY FAST”. Screamed at me out her minivan window by a middle aged Indian woman making a left across traffic in front of me. Still cracks me up.

Not a direct answer, but if you ever get a chance - go walk around a self-serve junkyard. This is where cars go when they finally just aren’t worth fixing anymore. It is eye opening. There are cars that you will still consider ‘new’ that have already given up the ghost (mainly Dodge/Chrysler, Hyundai/Kia, & Nissan). And you can’t help but think - WTF are these cars doing here, aren’t these still for sale at the dealership?

Conversely, there are also cars there so old you hardly recognize them (usually Honda, Toyota, and full size pickups from Ford/GM).

I’m super-out of date, so talking about the originals here.

For the Decepticons, I have to go with Devastator / the Constructicons. Something about “We build for EviL” is just so cartoon villian-y that I’ve always loved them. Plus, neon green & purple.

For the Autobots - my first transformers ever were Gears and Cliffjumper - two relative no-name minis, but they have a special place in my heart.

Landing my job. I had experience with a relatively obscure piece of software. Turns out the company had been looking for weeks and couldn’t find anyone. The guy I was replacing had a new job lined up, so they needed someone ASAP.
