Stupid CoWorkers

I work in a local hardware store. Recently, a new employee was hired to work at the store. On his first day on the job he announced to everyone that he was mechanical genius and smarter than everyone else. After several days on the job I realized he was a complete moron. First, he misspelled grease. He spelled it G-R-E-E-S. Second, he put together a wheelbarrow with the handles on backwards. The final convincing argument that he had the intellect of a 3 year old child was when he put together an extension cord with the same part on both ends(both ends could plug into a socket). When I told him he made a mistake he simply asked, “What’s wrong with it?”. All I could manage was a laugh.
