Yes, they are lame.
You know how when you run a race, they give you a t-shirt? It's got bad graphics and garish colors. You proudly wear it for a few years, because you think it looks bad-ass, reminding everyone what an awesome runner you are. Yeah, I'm sure you tell people, " I wear this shirt to remind myself of the commitment and sacrifice I made to run this race...blah blah blah" some crap like that. But let's not lie to each other here - you got it because you want to show it to others, to remind them that you are a bad-ass runner.
But eventually fades and stretches and sags and looks like sh!t. So you throw it out, because you don't want to look like an effing toolbag wearing some sad, faded, saggy, stretched running shirt.
Well, imagine if you had to wear that shirt for the rest of your life. And eventually people won't even be able to tell what the hell is on the shirt - the colors will be so faded and the graphics so blurred it will just look like you are wearing some crappy old sack.
Tattoos are for short-sighted people.
