A man walking by notices the sign and walks into the restaurant, sitting down with a smirk. The waiter asks for his order, and the man requests "white rhinoceros stew." Surprisingly, the waiter returns with a steaming bowl of exactly that. The man, taken aback, eats the expensive meal and leaves angrily after paying.

The next day, he returns with the same smirk and orders "bullet ants stuffed with dolphin meat." The waiter promptly brings him his requested dish. Once again, the man, surprised, eats his meal, pays, and leaves in frustration.

On the third day, he sits down and asks for "a lactating mermaid breast sandwich." After a few minutes, the waiter returns with two large duffle bags containing one million dollars. Ecstatic, the man exclaims, "I knew it! You don't have mermaid breast!"

The waiter politely responds, "We actually do, sir. We just ran out of bread."
