The guy who edited the Lloyd in Space page on Wikipedia must really like Recess... If a person voiced someone in both shows, it's mentioned, even if it wasn't a big role. As an example:
"Larry is another one of Commander Nebulon's aides. He is a purple humanoid who frequently acts childishly. Voiced by Eddie Deezen, the voice of Knarf, the leader of the Nerds in Recess."
I believe he was only in one episode of Recess... Really, a better "also voiced" thing would be Mandark from Dexter's Lab!
