After Felix and Oscar's bickering chases three consecutive guests out of the apartment, Felix becomes intrigued by Myrna's mention of group therapy and decides to attend, with Oscar independently deciding the same thing. The two end up banished to a separate room after disrupting the session with another fight. Afterwards, the therapist suggests both of them try role-reversal therapy to see each other's point of view.
This episode includes examples of the following tropes:
- Actually Pretty Funny: At the end, Felix chuckles as he tells Oscar that he imitated him pretty well.
- All Men Are Perverts: Marie, a woman from Myrna's therapy group, complains that she feels ogled all the time. She also tells a dream wherein she's standing naked before a group of men and they're only interested in what she has to say. Felix, who inverts the trope, sympathizes.
- Hypocritical Humor: Felix tells Oscar about the Rorschach test and asks him what he sees in a splotch of mustard, promising not to judge. After Oscar says he sees a duck, Felix calls him a sick man.
- I Have to Go Iron My Dog: When the two ask Miriam and Murray over again, Miriam says she might have already made plans for the day, and Murray claims he has to take the dog for shots.
- Inkblot Test: Felix asks Oscar what he sees in a mustard stain on the floor.
- Mirror Scare: Felix sets a mirror across from Oscar one morning so he can see how he looks at breakfast. The sight scares Oscar twice before he calms down.
- Shout-Out: The title refers to a song by Sammy Davis Jr..
- Speak in Unison: Felix and Oscar yell, "Look what you did!" at one another after Murray and Miriam leave.
- Swapped Roles: Felix and Oscar change roles in an attempt to alleviate their mutual hostility. However, while their impressions are fairly accurate, they both sometimes exaggerate each other's personality traits (Oscar [as Felix] does housework wearing a tuxedo while Felix [as Oscar] dunks his cheap cigar in Oscar/Felix's glass of wine).
