While doing a little Q&A for her Bongo Virus promotion, Paris Hilton was caught off guard by a cheeky prankster. The "reporter" offered up some gifts to replace items stolen from her home in last month's burglary before flashing his underwear at the celebutante.

Surprisingly, Paris was shocked and tried to run off while the perp was removed from the room.

I guess this explains Paris' penchant for not wearing panties, she's scared of them!
