Lumpus' Last Stand
I just wanted to say how awesome it is that Heffer from Rocko's Modern Life made a cameo in the episode "Lumpus's Last Stand".
Heffer was the one who said Lumpus locked him in a room and stole his title as Scoutmaster.
You know it's Heffer because of the following exchange:
Lumpus: I'll get you for this, Cow
Heffer: Steer.
