While we're still on the topic of characters with similar job descriptions and character traits can I point out that both Bree's stalker (George) and Susan's stalker (whats his name from Season 7 who wanted to give her a kidney) were both inpharmaceutics.
George was aPharmacistandwhat'shis name soldPharmaceuticals. lol. I think someone in the writing crew had a bad experience with a pharmacist in their past and has projected it into the show. lol.
