Well, the strange thing was that Zoidberg's claws functioned just as well as human hands, though no one was exactly sure how. But he gestured with them as he spoke just as people would with their hands. He didn't notice the guy looking at his claws - it was probably something that happened often enough that Zoidberg tuned it out.

"Home? No, my home is on Earth!" He clarified, waving a claw. "In... uh... a mansion..." he quickly added. Certainly not in a dumpster or anything. Oh god no.

"Well the Earth is full of humans and row-bits and some other weird creatures, maybe."
