Er. Um. Sorry.
Seriously, I thought you were someone else ... As reported by The Arkansas Times:
Best reason not to work under your car
In August, a Springdale man, angry at his girlfriend, went to the trailer park where she lived, saw her doing some mechanical work under a jacked-up car, kicked the jack away, causing the car to fall, seriously injuring the woman underneath it. Man was charged with assault, among other felonies, and got no satisfaction from the crime since, uh, it wasn't his girlfriend the car fell on. Some other woman. No word on whether his plea was, “Oops, sorry! Meant to kill somebody else.”
