Slogan T-shirt makes people actually see you?

I love Slogans and quotes on T-shirts, they say something about you, if you decided to put it on your chest, it's more of a Message to the World. It makes people actually notice you, and keep an eye a second longer, just to read what's there. I'm not too sure of massive belt buckles on guys, do they want to bring the attention to the lower parts?
I heard lately, that there are Hoodies and T-shirts with the Comic Story printed on them, with an action plan you can follow, but will you need to stop the guy who wears it to read it through? 'Sorry, I haven't finished yet...'
