Last Friday, a masked intruder broke into a woman's home in Albuquerque, New Mexico. Despite his rudimentary disguise -- a purple bandana pulled over his face -- the homeowner could tell it was her grandson, who had robbed her before.

So, she ripped off the bandana to confirm her suspicion. The, identified as 22-year-old Thomas Clark -- shoved her to the floor, grabbed her purse and ran. Police arrested him at his parents' home a short time later.

How do you treat your grandmother like this ? This guy is definitely a candidate for BIG DUMMY OF THE YEAR.
