Batman really like his grandmum on the 100% cotton Batman 66 Theme Background Royal Blue T-Shirt! What do you mean that isn't what this great, vintage style shirt is about? All of those 'Na-s' are mimicking the sound of the Adam West theme song? I don't know about that, man. I don't know! The Batman 66 Theme Background Royal Blue T-Shirt is still an exceptional shirt for you fans of Adam West. Nobody messes with him that's for sure!
