Probably something to do with baseball

I have a few friends who have used "baseballXX"(any nukber in place of X) because it was thebfirst random activity/word/thing that popped into mind, and i rememebr a while ago that was like one of the top 10 most used passwords on the internet.

I jist find it kinda funny that most people jump to "baseball" as a random thinf no one would guess, because now it's pretty much my first guess if i need to crack a password(followed by "baseball2, baseball3 all the way to baseball99)
