Mr. Cat's show has the characters based on himself and Kaeloo make out, get married, and adopt a dog. The real Kaeloo witnesses this and flusteredly points out to Mr. Cat that the two of them don't own a dog in real life. At first it seems like an I Take Offense to That Last One joke, but if you think about it, of course Kaeloo wouldn't deny wanting to kiss or marry Mr. Cat!
