I was watching "Why Must I Be A Chrustacean In Love", and suddenly something connected. Before the start of the Claw Plach match Zoidberg asks Fry whether disembowling is fatal for humans. First time I heard it, I just took it as a joke about Zoidbergs horrible knowledge about anatomy. Then in Roswell we see that disembowling actually isn't fatal for Decapodans. So Zoidbergs question was legit.
Similarly someone once posted about his "Chopping him right here, in the gonads."-line. In "Fear of A Robot Planet" we see that Zoidbergs species may have their gonads in the neck-area.
I have a feeling the Handcrafters thing will show up again in "The Devil's Hands are Idol Playthings".
So, anybody else noticed something that just looked like an obscure joke at first, but later turned up again?Or am I just bored?
