No sooner does the much-hyped Coming Gay Prom story get underway than we take a detour into "Sundays with Crazy Harry"-land. No wonder the United States Postal Service is on the brink of bankruptcy, with goldbricks like carrier Klinghorn on the payroll. I'll overlook John's improper grammar in panel 4, to focus on what I hope is the real gag today (because the punchline sucks, as usual): in the penultimate panel, John is expressing optimism about the state of his business; meanwhile he's holding a comic book titled The Grim Ghost. Irony?
It gets better (hah!): Maybe TB is a little more clever than we give him credit for! A little more "komix" research turned up this factoid courtesy of Wikipedia:
An earlier and somewhat similar character called the Gay Ghost has since been named the Grim Ghost due to the modern connotations of the word "gay".
Is Batiuk going meta on us? Naw…probably just a coinky-dink.
