I heard this one from a friend... A blonde enters a parallel universe where the Aryan's are considered a minority. She walks into an appliance store, approaches the man behind the counter, and says ""I'd like that TV please."" The cashier replies ""Sorry, we don't serve blondes."" The next day, she woke up, filled her hair with charcoal, and went to the same store and asked the same man for the same TV. ""Sorry, we don't serve blondes here."" The next day, she got up, went to the hair salon, get her hair dyed red, and went to the same store and asked for the SAME THING. The cashier responded ""Why do you keep coming back if you know we don't serve blondes?"" At this point the blonde was furious. ""How the hell do you know I'm blonde?"" The cashier looked her straight eye, and explained, ""that's not a TV, that's a microwave oven.""
