I love this shirt simply for its shock value. I mean, if you're going to a fancy banquet with aristocratic executive types, is there really any other shirt to wear? I also find it hilarious to wear to family functions and PTA meetings, and if you have Larry Flynt status it's also fun to wear to court proceedings.
It's up to you if you want to do cocaine or not, that's your business, but even if you don't do cocaine and have never touched the stuff, this shirt is funny and will get a rise out of your audience for sure. This world needs a sense of humor, right? ;)
