I could make a joke about your attention to detail (), but seriously, it's 'bad' only in that we are discussing sitcoms (I would call QC unquestionably one of those), so familiarity with all other sitcoms is beneficial.
I imagine each of the gay characters may well have coupled up either at some point or as of now, but the original premise was single straight female and her single gay male roommate (who was the comedy's straight man, get it?), and their two best freinds, a single gay man, and a married (crazy rich) straight woman.
