Anyone living in the DC area recognize the joke behind the name "Otterloop" (at least I hope they do; it took me forever to get it myself). It's a play on "Outer Loop", the outside, counter-clockwise ring of DC's Beltway. You would most often hear it in a sentence with the word "delays", as in, "Delays on the Outer Loop start at the Springfield Interchange." If you don't live in DC and aren't familiar with the "Outer Loop" be glad, it's usually a nightmare. And the "Springfield Interchange" is even worse.
Looking at the map of the Beltway provided above and comparing it to Mr. Otterloop's head I see a resemblance, kinda. But mostly it looks like an upside-down cartoon dialog balloon.
