Corrected entry: When Mr. Brown was reading the paper, he saw the article offering a $50M reward from Mr. Drummond. It should have said $50K. The article was suggesting that he was offering a $50 million reward.

Starring: Conrad Bain, Todd Bridges, Dana Plato, Gary Coleman
Continuity mistake: By this episode, Mr. Drummond has already remarried Maggie. Maggie and her son have moved in and Arnold and Sam share a room, where Willis has a room elsewhere. In this episode, there is no mention of Maggie or her son. Willis is back to sharing a room with Arnold. In fact when its decided that Charlene will stay, Arnold makes a joke about the bathroom saying that Kimberly won't be the only girl in the house (what happened to Maggie?).

Suggested correction: Season 6 was plagued with episodes being aired out of order. "The Houseguest" was actually the 12th episode produced (production code 612) and comes before The Wedding episodes (production code 620 and 621).
Philip Drummond: Good morning, Arnold. Rise and shine.
Arnold Jackson: Better not let Willis hear you say the word "shine." Back in Harlem, that's fightin' talk.
Trivia: Kimberly's school is the same school from the Facts of Life. It even has the same classmates and Kimberly shows up sometimes.

Correction: "M" for thousand isn't atypical, but has become far less common in mainstream reporting. M for thousand and MM for million, from the Latin, rather than K for thousand from the Greek. https://www.chicagomanualofstyle.org/qanda/data/faq/topics/Abbreviations/faq0094.html
