Those who thought Urinetown would be the most irreverent musical to hit the D.C. area never bargained for Cannibal!

Landless Theatre Company’s latest production (clearly to some degree a satire of Oklahoma!, as its “Shpadoinkle Day” number can only be a send-up of “Oh, What A Beautiful Morning!”) follows the unassuming Alferd Packer, who leads a motley crew of gold-seekers into the mountains, where they are met with less-than-desireable circumstances, from a mythical Cyclops to, well, the prospect of having to eat each other to survive. The work, based on a true story in the loosest sense of the phrase, is the brainchild of “Southpark” creators Matt Stone and Trey Parker, and, like their epic “Southpark: The Movie,” is a bawdy send-up of the musical genre it occupies.

It’d be easy to nitpick away Landless Theatre’s production; there are staging missteps (a solo “tap-synching” number, for example, doesn’t work), a chorus lacking a full-bodied sound, and a general amateurish feel that at times calls to mind what might happen if a couple of college theater buddies decided to put on a basement production of a cult favorite like Buffy: The Musical or The Rocky Horror Show. All of these issues, however, are eclipsed by the hilarity of the work itself, the general enthusiasm of the participants, some casting coups and a lot of creativity.
