Buzz Aldrin has a guest appearence in this episode and even voiced himself.
Prickly asks Buzz Aldrin, that how did he get his nickname ("Buzz"), It goes unanswered. The story behind Aldrin's name is that when he was born, the younger of his two older sisters (who was then-19 months old) couldn't say "Brother", and called him "Buzzer" (later shortened to "Buzz") and it got stuck. He preferred the nickname instead of "Edwin Jr." (his real name).
