This is Muffel Buffel's story as written on his tag:
"His family originates from the last ice age. And his humour is ancient, too. When he tells a joke, everyone grits their teeth... Two buffaloes are standing at a waterhole. One says to the other: “Chilly, isn’t it?” the other one: “Yeah, the crocodiles were here already.” Or: Two monkeys are in the shower. One says to the other: “Ooah oogah hooaa,” the other one: “Then make it colder.”"
