Its about cars though...Okay, so these two college guys buy a new Volkswagon Beetle in the 1970's. So they're driving in the backroads on a rainy, muddy dy, to go back to Michigan from Chiacgo where they bought the car. Now they get a flat tire, and stop to repair it. Now the happen upon a small German immigrant town, and a Volkswagon repair expert. So they pull up and he walks up and says to the in his German Accent "You need ze tire repaired?". Now how did he know that they needed a tire without inspecting the car?
