This may be the most disturbing/disgusting thing I've ever seen. Unless you have video surveillance, you never know the things that go on around your house. Dave and Sylvia Dungan of Salinas, California, recently installed security cameras and got a surprise of a lifetime when they saw this man LICKING their doorbell for THREE HOURS!!! I've heard that people have weird fetishes but this is down right CRAZY!! The door licker, 33-year-old Roberto Daniel Arroyo didn't attempt to enter the home but he did pee in their yard. -Police say he could be hit with misdemeanor charges for prowling and petty theft.
