Question: At the beginning of the episode, John Redcorn pretends that he is at the Gribble's house because he has gingko biloba for Nancy's headaches. Peggy seems awkward and makes the "Uh-huh, sure, I've heard of that" comment. She doesn't yet know about John and Nancy having an affair - she finds out later in this episode - so why is she uncomfortable at this point?
Question: Hank bears no resemblance to his father, but strongly resembles his mother. Bobby bears no resemblance to Hank (or seemingly Peggy), but bears a strong resemblance to Hank's father. Is it actually possible for a person to bear such a strong resemblance to one of their Grandparents if they are only getting half their genes from that Grandparent's child and that child bears no resemblance to that particular parent?
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.
