Funny shirt.  I also like the fact that 555 is the fake phone number for movies and so on.  It's also a recording studio in Flagstaff, Az, but the site seems really boring so I'm not going to link it.  If they had some music from their artists on it I would (not that I would listen to the music, but I would link the site).  What is slightly more interesting is this art studio in Detroit, MI httphttp://www.555arts.org/ .

Of course mentioning Detroit reminds me of the Michigan girl who broke my heart the most.  She always used to tell me the worst parts of Oakland (where I live) are like the best parts of Detroit.  Oh, well.
