Tell Me Where It Hurts - S9-E7
Corrected entry: Eric is supposed to be in the Air Force but his hair is so far out of regulation it looks like he hasn't cut it in months.
Walk Like a Man (a.k.a. Don't Call Me Mikey) - S9-E4
Corrected entry: Toward the end, when Susan is trying to convince Abby to go clubbing with her, Abby has a wedding ring on her left ring finger. Abby isn't married on the show.
Correction: Actually she WAS married on the show. Some people still wear their wedding ring at times even after the divorce.
Correction: Eric was developing bipolar disorder, and as we later learned, had gone AWOL. Trimming his hair was likely the last thing on his mind.
