blue screen of death (BSD) shirt
This error screen is the cause of over 70% of my profanity. That and the blue shells in Mario Kart... (you know what I mean) This great shirt always evokes great responses from people who "get it". You'll get people sighing, telling you of data loss stories, game crashes and others will just give you a knowing smirk.
GET LOST IN THIS PENNY ARCADE TSHIRT! SLIDE FOREVER FROM PORTAL TO PORTAL AND WIND UP IN NEW FUN AND INTERESTING SITUATIONS YOU CAN'T CONTROL! THIS IS FUN!
TELLING TIME AND WHERE YOU ARE IN YOUR HEAD AREN'T AS EASY TO READ! MOODS ARE EASY TO AVOID WITH THE IWEB CONVERSATOR BY MASS EFFECT TSHIRTS! SHOW YOUR TECHNICAL SIDE ON SOMETHING LIKE A SHIRT!
Ok, this tshirt totally appeals to me for the obvious geeky reasons. It's got "mu" and "pi" in the same sentence. Combine that with a cool picture of a mutant cow, for some reason it just got me laughing.
Useful advice in any language and any country.
