Question: Can someone explain to me what a red shirt means? I know in one episode when someone broke Bill's high school touchdown record that Hank mentioned that Bill was red shirted because Bill went into the army before he graduated thus compelled Bill to go back to high school and try and break the record again.
Question: Hank says that Boomhauer has known Peggy longer than he has. How did Boomhauer and Peggy meet first?
Question: How could Bobby and the rest of Mr. McKay's class have showed up at Strickland Propane without Hank knowing? Surely the students would not have been allowed to go on a field trip without a parent's permission. If Peggy had signed a form at some point, she mostly likely would have mentioned to Hank that Bobby would be at his workplace.
Question: Two questions about Nancy and John Redcorn's affair. First, has it ever been explained why Nancy had an affair for so long and didn't leave Dale? Her relationship with John seemed to be more than just fun. Also, have the show's creators ever said why they didn't do an episode where Dale finds out about the affair?
