The week Keith Urbanwore his 'I Am the Stig' t-shirt, it had everyone talking. What is the Stig? So I did some research to find out. Still don't know the answer? Find out here. But it also got me to thinking: Keith wears a lot of weird t-shirts on American Idol. And it's not just Idol. Where does he get all those cool shirts? A lot come from Ames Bros clothing.
