A skunk and a rabbit were running through the woods and accidentally they collided with each other. They both got amnesia from the crash.
“Who am I? What am I?” said the confused rabbit.
“Well, you’re one such… with a short tail, long ears… “
“I guess!” shouted the rabbit, “I’m a rabbit!”
“And what am I?” asked the skunk.
“Ah! Yes. You’re one such hairy, smelly, with a strip in the middle… “
“Wow!”, yelled the skunk, “Probably I’m an ass!”
