I also have a Tool shirt, 2 actually, but it hasn't attracted any nutjobs, except, all my friends are more or less insane, might be why

[link] "pick a Tool fan out of a crowd easily, by looking for a college student who speaks of issues which he has little to no understanding of and constantly reeks of bong water

If you think see I Sweden classic metalheads whit jeans, letter jacket a, long hair from MTV era, well or's not so often here in a north, but we have many who had metal band t shirt or hoody

"Tool" is another word for dickhead, so maybe they don't know the band and think you're one of them?

Sounds like your typical Tool fan.

I have a Tool shirt that I will never wear out because without fail anyone who says to me “cool shirt” turns out to be a nut job. Don’t know what it is about that one

Same here but I only wear them in hiding
