Absentee Actor: More like Absentee Character; as noted below in Body Horror, Trace Beaulieu doesn't appear on-camera for this episode, since Dr. Forrester has been turned into a skeleton puppet. (He still does the voice, of course, as well as presumably the puppeteering.)
Actually Pretty Funny: Crow and Servo make a Joel puppet with the apparent intent of feeding it to a puppet scorpion. When Joel sees it, he's impressed by the obvious effort that went into it.
Body Horror: The Mads after trying to make a cold fusion Walkman. Erhardt's head is swollen and deformed, and Forrester is reduced to a skeleton. (Also since they don't get better by the end, the only time Trace Beaulieu appears on screen is in the title sequence!)
Gag Dub: Joel and the Bots educate the viewers in the Spanish language in homage to the Mexican setting. However, most of what they say is Gratuitous Spanish (mostly the names of Tex-Mex food items or place names), and the length of the translations given don't even come close to matching the words they're uttering.
