This episode very much centres on Dale, which is great, as he is one of the best characters (and one of the funniest) in the series.
After the years of Dale believing in even the most ridiculous conspiracy theories, it is amusing to suddenly see him as a flag-waving patriot who won't hear a word said against the Government.
It is indeed a sudden change of character, rather like the previous season's 'The Redneck on Rainey Street'. But if you're prepared to look past the sudden change (and his eventual sudden change back), this is a really nice, enjoyable episode.
Hank's dismay at finding his new drivers license states him to be female, and his subsequent futile attempts to get it corrected, makes for a great parallel plot, and the two tie up nicely in the end.
