I must confess, making fun of accents is petty. But…. normally when one makes fun of an accent, they are laughing at it because it is foreign, and foreign ways can seem pretty silly, and thus it implies that even geniuses from the other culture are primitive silly nitwits. In this case, it was aimed at them for being nitwits to being with, and just having fun with their way of talk (which was as much slurring and poor enunciation as it was actual accent).

Which, in the end, is also petty. Hah!

The golden retriever line is pretty good though. :)
