The title is a reference to Manic Monday by The Bangles.
Last episode of the series.
When a reboot of the series was announced in 2023, the producers stated that after the real-life deaths of Brittany Murphy and Tom Petty, the characters of Luann and Lucky would not be recast for future episodes. While Johnny Hardwick had been signed to return as the voice of Dale Gribble and had begun recording lines, his real-life death in 2023 from natural causes left the character's future uncertain. Mike Judge and Greg Daniels have said they're considering whether to recast Dale or to retire the character as a tribute to Hardwick.
