Potential Nazi

Alright, listen up, you cotton-headed ninny muggins. This "joke" is banking on stereotypes. Adidas, Puma, and Volkswagen are all German brands. Get it? So, the joke implies that someone who likes these brands might be a Nazi. Nazis were the worst dudes from Germany back in the day. Also, you should know that Germany makes good stuff and you should probably go there to get some culture you illiterate.
