A joke about selling hairy crabs

This is a cold joke! It's a homophonic stalk! Shrimp and blindness! Then it seems that crabs are cute, hahahaha. Maybe different people have different reactions to different cold jokes. This is a joke, a brain teaser! "A sheep was eating grass, and a wolf passed by, but the wolf didn't eat the sheep." For example, I just heard this! This sentence hit the animal! The answer is shrimp, hahahahahahaha.
