In an recent report by the Society for the Promotion of English Language Humor it was revealed that most of the world's English speakers don't find English humor funny. The most cited reason was "Humor Subject Matter Unintelligible" with "Vulgar and Immature To No Purpose" a close second. The survey was taken in every major English speaking nation in the world, which is to say every English speaking nation save England.
Website "The Spoof" graphically portrays the problems with English humor.
Relying heavily on "potty-humor" and childish fictional names like "Hugh G. Ereckshun" curtails adult interest and English humor's constant references to people named Cheryl Cole, Prince William and sports teams like Manchester United limit a joke's appeal to the few score people who know these names. The non-English who aren't turned off by the headlines rarely make it past the topic sentence which usually run along the lines of describing Cheryl Cole in a sex act as written by a schoolboy who's never engaged in sex.
Located somewhere in the ocean, England is a small island nation shrouded in fog, much as it's glorious and ever-receding past is shrouded in the fog of time. Part of that glory was a man named William Shakespeare who penned dozens of plays at the turn of the seventeenth century, many of them comedies still produced today. A 360-year comedy "Ice Age" set in in which England produced not one shred of humor. The Ice Age was thawed briefly in the late sixties through the early eighties by a comedy troupe known as "Monty Python's Flying Circus."
With the demise of Monty Python England became increasingly isolated in the humor world except for jokes about the royal family. But while English people found humor in the jokes' context, the non-English found that the joke was on the English themselves who foolishly support an aristocracy that produces nothing of value at enormous expense to themselves.
