- Keep Circulating the Tapes: The game is no longer for sale digitally or physically, due to Telltale's distribution rights expiring. The PC version can still be found used for pretty cheap, however.
- Averted in 2020 as Steam has it back up.
- Prop Recycling: A cow in "Muzzled!" is the same cow from the "Midtown Cowboys" segment of Sam & Max: Freelance Police. Although it's only briefly seen, and hidden behind a door, the recycling is noticeable because the two games have distinct visual styles.
- The Other Darrin: Ben Whitehead takes over as the voice of Wallace.
