In this parody song he means in the beginning that Sid Lumpkin and Kyle Orton were the only two QBs that worth a damn in the Chick A Go Bears history. Plus McMahon (Two rings bears 85 and Favre's back up in 98).
That's actually a reasonable law, when you consider it's a 2 lane super hi way, with no speed limit, and although I've never seen it, I'm guessing a small berm. I saw something on the History channel, and it's also a rule that you must drive in only one lane, as the other is for passing only. They also constantly perform maintenance on it, so a good deal of the time, you are restricted by a speed limit.
