Homer's POV after the seat-less chair accident varies. When viewers see Homer's POV, he is too far back; his belly and his crotch are visible, which would be impossible for the position he's in during the third-person view shots.
Homer converts the garage to a "snuggle dungeon" and later Marge says she can't find the washing machine. However, for the entire series the washer and dryer has always been in the basement.
