The background when Urd and Skuld realize that Keiichi and Hild are taking a bath reads AH! MY GODDESS in English.
Mahler is another alternative spelling for Marller introduced in the episode.
Ending theme: "Koibito Doshi"

In the English version, the closing credits still display the other song.
Sayoko and Belldandy sing the theme songs from the first season including new lyrics for the English dub.
Jingle Bells is playing when Sayoko is walking with Keiichi.
This episode explains the Goddess Licenses. In brief:
Belldandy: 1st class, 2nd category, unlimited
Skuld: 2nd class, 1st category, limited
Urd: 2nd class, Admin category, limited
While Marller celebrates from retrieving the urn, the scene pans to another part of the cave where you can see the legs and skirt of a woman: a sneak preview of the demon queen Hild!
Skuld's angel, Noble Scarlet, is officially introduced in the second season.
When Keiichi makes his phone calls he gets the following companies:
Tokyo Broadcasting (TBS)
This is the first episode where Keiichi "kisses" Belldandy on the lips, even though it was to save her life.
Gamer at heart
Skuld is using a gray Sony Playstation controller that even has the button names in the correct position. When she hooks up the computers, there are several gaming consoles.
Sayoko still calls herself the campus "Queen", even though she formally lost her title to Belldandy.
Throughout the course of the series, Belldandy has told Sayoko the truth about her being a Goddess. Needless to say, Sayoko doesn't believe her.
Urd's videotape is a Sony Betamax format which went obsolete in the 1980's, but Keiichi has a video player for it to go with his old television with the dials.
The chocolate heart that Belldandy puts together has a label that says: Happy Valentaine
Aoshima is Sayoko's cousin.
Megumi hitchhikes and then takes a ferry to Nekomi which she says is in Kantou area (eastern section) of Honshu (mainland of Japan). This is consistent with other sources saying they are in the Chiba Prefecture.
However, Megumi brings groceries from Hokkaido, which is the northern island of Japan. That's a long ferry ride, and might be at odds with the manga event concerning Keiichi's father driving all the way from home and having to go through the Seikan Tunnel underground for 33.5 miles.
