As a glutton for Mexican food, this reviewer enjoys cheese-cutting as much as the next person. But what transpires in this burrito of fallow humor and sex coverage leaves one pining for the mute talents of Randy DeTroit, and can best be summed up in the line credit, "Nina Hartley as Diarrhea."

Hartley, along with three other ladies named Caca, XXlax and Evil Cuntessa, possess this ungainly ability to fart a man's head off, literally —a running gag that runs out of gas about the second or third time around. About as funny as a fart in a rubber suit, one might say.

More's the pity because this is a technically-sound, well-shot feature. If any of the other scenes had come near to the texture of the Blake Palmer-Alyssa Allure ass coupling, even this brand of practical joke would have safe toxic levels.
