When Bob and Emily go to the marriage counselor and she suggests role reversal, she asks Bob what she (Emily) would be doing when he (Bob) gets home. Bob replies that she would be on the sofa "putting up my hair". This makes zero sense as both Bob and Emily have extremely short hair that couldn't be "put up". Also, Emily "putting up" her hair has NEVER happened in the entire run of the show. NOTE: Probably strictly a sarcastic remark with no regard to actual hair length.
