When I was in the Boy Scouts (really just an excuse to spend a weekend or two in a tent away from my family) we went through some extensive training on how to treat a US Flag.  There are very specific rules for how to handle, display, and treat flags.  I am happy to report that this t shirt features the flag in the correct orientation and is thus free of violation (there is a rule against wearing a flag as clothing, but not, apparently, against wearing a representation of a flag on your clothing.  Otherwise every US soldier would be in violation).  Check out these flag violations.  Apparently there is a whole subculture of people who like to bitch people out about flag violations.  

By the way, if you are an evil mastermind bent on world domination (like me) you can design your own flag (to a 4th grade skill level) here.
