A man dressed as Gumby made such a horrible attempt at robbing a 7-11 store that the clerk thought it was all a joke. The assailant told the clerk he was being robbed then fumbled inside his costume as if he was going to pull out a gun. He ended up dropping 27 cents on the floor and being told by the man behind the counter “not to waste his time.”

The 7-11 clerk didn’t report the encounter, but told his boss, who called police after watching the encounter on surveillance tape. Detective Gary Hassen told San Diego’s 10News that the clerk had never heard of Gumby and described the costume to police as “a green SpongeBob SquarePants.”

The police are taking the matter very seriously and are looking for the suspect. People of San Diego should be on the lookout for, well, Gumby. There’s a $1,000 reward.
