In the seventh episode of Down and Safe, Michael, Liz, Scott, and Amal discuss Duel, the seventh episode of Blake's 7, and manage to get through at least fifteen seconds before they mention Arena, that Star Trek episode with the same plot. This same epic restraint to avoid cheap jokes is, of course, shown in the rest of the episode too.
This is a useful reminder that this podcast is very probably not safe for work, and may contain mild spoilers for the rest of the Blake's 7 series throughout the episde (we keep major spoilers to a spoiler section of the podcast that we give warning is going to be particularly spoilery.) This episode also contains spoilers for Wacky Races and Babylon 5.
