Tevin Bartleman is a character who appeared in Double Down. After Greg made up Curtiz Litz, Susan saw Tevin at church and told his parents that they owed her some apples. However, Greg felt sorry, because Tevin Bartleman was a nice kid and his family volunteers at the soup kitchen downtown every Saturday morning. Later on that year, Susan joined the Fundraising Committee, which was headed up by Mrs. Bartleman. It didn't take long for Susan to figure out things from that and Greg lost TV privileges for a month as a punishment and when Tevin saw Greg in the hallway, he punches him and calling him "Jerk!".
