"Gee Sven, there is nothing much here, have a look in the shed out the back."
"Hey Lars, there is only some old sheep heads out here and they are a bit moldy and besides, they are covered with all this old wool. What are we going to do?"
"I know Sven, let's toss them in the fire and burn off the mold and wool."
"Hmm Lars, there is still some wool and mold left."
"Well, toss them in the fire again."
"Nope, still got some mold and wool left on them."
Sven, do I have to do all the thinking, toss them on the fire again and keep doing it until all the wool and the mold is gone."
"OK. Lars, I've got it now. The heads are clean. They don't taste too good the way they are though. A little smoky. What are we going to do now."
"Well Sven, let's put them in the smoking shed for a few days where we smoke the salmon".
A couple of days later Sven reports that the heads taste better but they are not too good cold.
Lars says, "OK Sven, stick them in the pot and we'll boil them up, that should warm them through."
The heads are then boiled. Now Sven tries them and says, "hey, they do taste better but one head is too much for me to eat. Have you any ideas Lars?"
Lars says, "OK Sven, just cut the head in half and eat one half then."
