San Francisco resident Henry Wolf is suing BMW North America and Corbin-Pacific Inc. for causing an erection that has lasted for two years.

Wolf alleges that a four-hour ride on a 1993 BMW equipped with a Corbin seat caused a priapism, a medical condition in which an erect penis does not return to its flaccid state. The erection, which reportedly began in May, 2010, has caused Wolf emotional and mental anguish. Apparently, his condition has also prevented him from engaging in sexual activity; an odd detail we thought, having fully expected that the opposite would have been true.

The Wolf lawsuit is seeking compensation for lost wages, hospital expenses, and general damages. And while every party involved in the lawsuit begins to ramp-up their case, we’re predicting a healthy rise in the sales of older BMWs and Corbin seats.
