Mr. Dixon was only mentioned in two episodes. In The Curious Case of Mr. Dabney in the epilogue, Bob said he was a science teacher when Mr. Dabney really was one. PJ and Gabe ran off, scared out of their minds. Amy then said Mr. Dixon was really a music teacher. Teddy called Mrs. Dixon in Special Delivery and asked if their daughter could come to Charlie's third birthday party, revealing Mr. Dixon has a wife and one kid. He is one of the Duncans' neighbors.
