A one night stand in Hell's Kitchen proved particularly unsatisfying when a thug stopped mid-coitus to rob his partner of a BlackBerry and $40. The two had just met and went back to the victim's place on 43rd Street near Ninth Avenue at 7:15 p.m., according to the Post's police blotter. They were going at it when all of a sudden the thief took out a knife, grabbed the 34-year-old victim's valuables and left. Before even finishing! Scant information on this one, unfortunately: no mention of the victim's gender or where the thief kept his knife (was he wearing a holster?). But then again, you might not want to reveal the juicy details to a cop either.
