Is this shirt funny or tasteless and offensive?

http://www.8ball.co.uk/tshirt/3/78990/T-Shirts/Offensive-T-Shirts/Hitler-European-Tour-1939-45/ I that its absolutely hilarious, and his shirt ordered 8 more at that site, I've just ordered one! Its brilliant! Although the shirt is clearly intended as a joke, apparently a lot of people have complained about it. So what would you think if he saw someone in the street with this shirt?

Buy one for yourself, your wife and children if any, and wear it on a meandering while Saturday at Golders Green.
