Well I like off-beat humor, for example from Max Cannon's cartoon character called MilkMan Dan, the The Three Stooges, Marx Brothers, etc. If you can't enjoy life and laugh frequently, what the heck is the use?
I think a lot of things are funny or interesting.
I like to understand why people do things, and how stuff works.
A pet peeve: people not paying attention to what they are doing/quality of work. For example, I've had a lot of landscaping done around my house. For almost every 5 things fixed, one thing is broken. I have to do a "recon patrol" to find the broken sprinkler heads, cans of coke mere feet from the trash cans (feeding armies of ants), cigarette butts in every nook and cranny... hmm..
Here's a funny picture of a guy we were behind on the way to work: this dope was actually reading the paper while he was driving, and oblivious to everyone giving him strange looks as they passed. What happened is that the cardboard tube could not handle the weight of the carpet, and eventually bent. Pieces of carpeting were flying off as it ground on the freeway. We had to pull off, but I would imagine about 5 more miles, and all of it would have unloaded. I wonder what happened when he got to the installation location: " uh, it was on the truck when I left, I don't understand". This dope could be carpeting your house next week! Another vote for the minimum wage.
Something really nuts, the baseball season just started. They are having the first game here. There are going to be "eight first pitches"... WHAT? So you buy a baseball that was used for the first pitch, but it can be one of eight?
Sounds like the "first pitch" means nothing now. Weird
Some more silly stuff: Lately the news has been reporting that you should buy your gasoline in the morning. This is because it is colder and denser, and you get more "gasoline molecules" in a gallon of cold gas than warm gas.
Well, if the gasoline was really cold in the morning and really hot in the afternoon, that would be true. But all these self-made scientists have neglected to realize that the temperature of the ground, where the gasoline is stored, varies only slightly from winter to summer. About 4 feet down, there is rarely a difference of 1 degree from hottest summer to coldest winter. (Think about it, if the ground 5 feet down got to 90 degrees in the summer, we would all be dead, all the plants would be dead, all the ice would be melted).
