We've all heard of shopaholics that get excited by a good deal but a Louisiana man has been taking his love of Walmart to a whole new - incredibly disturbing - level.

Travis Keen, of Monroe, La., was arrested on Tuesday and charged with public obscenity after he was spotted by police driving around a Walmart parking lot with his private parts exposed, RadarOnline.com has learned.

The 28-year-old's explanation for his lewd behaviour was that he "gets aroused," while shopping at the retail giant.
