Dwight was being rude as hell in "Saturday"

He came into his friends house and stuck his finger in the peanut butter jar, he was constantly being rude to Roseanne and looking down on her for being a woman, every other second when he was around Roseanne he was saying something rude. Like "Why you wasting your breath talking to her about motors Dan?" "I say if you can't find the fan belt you shouldn't get behind the wheel" "I tell you what i'd do if i was in charge i'd take all your little licenses away and put you women on public transportation where you belong".

Then he told Dan "I get down on my knees every night and thank the good lord up above i'm not married to that woman", Dwight seemed like a nice guy in the other few episodes he appeared in, but in "Saturday" he was being downright rude and nasty towards Roseanne.
