Gloria Poses in the Nude

S2 E2: Mike's artist friend, Szabo, is coming to the Bunker's house for a visit. Archie is a bit perplexed for two reasons. First, he is Hungarian. The other is that he sketches models in the nude. Szabo gets a great idea that Gloria should pose in the nude for him (an idea Gloria is all for). However, Archie is dead set against it and Mike doesn't seem to have any problems with it.
