Why does it have to be a woman?
Because it's a stereotypical joke
What makes the joke amusing is that it's surprisingly accurate for a surprising amount of women. That doesn't make them inferior, but it's a funny realization. Equally a similar joke about men that's equally amusing and insulting should be equally welcomed by the men who enjoyed this post. Sexism isn't funny, humor is.
Can't take a joke can we?
I know a lot of girls that can change tires, not including myself though.
I get that it's sexist but it's still pretty funny. I know how to change a tire now but this behavior was spot on for me when i didn't a few years ago, which is pretty hilarious.
I'd downvote this but that's probably what i'd do
Haha, true for me. I could probably do it if someone talked me through it though.
