My grandmother is 71 years old and wears a black Metallica t-shirt!Try to top that...
"OMG COLDPLAY ARE MY AMERICAN IDOLZZZ"
A guy I know from my grade is absolutely obsessed with 3 Doors Down. Not long after The Better Life was released, he bought a Superman t-shirt, and actually changed it to say "If I go crazy, will you still call me?" below the logo. I like the group, but that shirt fell just a bit short of being creative.
He wrote it BELOW the logo? Well that wouldn't make much sense.
