Seems like this chapter was never adapted into anime. Bit of a shame cause it was funny.
Tsubame is like the Dr. Tofu of Urusei Yatsura. He seems important but he rarely makes an appearance. This makes it more unfortunate that some chapters featuring him were never adapted into anime.
Tsubame and Sakura really do look like Godai and Kyoko here. I think Maison Ikkoku had a decent number of chapters out by the time this chapter was released.
