This was the first episode featuring Luis Avalos as a regular, where his character name was Roberto. He'd also play Dr. Doolats (a parody of Dr. Doolittle) and Igor (the Mad Scientist's dim-witted assistant). The Electric Company was the Cuban native's first starring role in a TV series, though he'd later star in a number of mostly forgettable TV series from the 1970s through the 1990s. The bulk of his success came mainly in theatrical and made-for-TV movies. Luis also guest-starred in numerous TV shows, including Full House, ER, Walker Texas Ranger, JAG, and Archie Bunker's Place.
