Song of the king

Well I was wandering along by the banks of the river when seven fat cows
came out of the Nile
And right behind them fine healthy animals came seven other cows,
skinny and vile
Well the thin cows ate the fat cows which I thought would do them good
But it didn't make them fatter like I thought a monster supper should
Because the thin ones were as thin as they had ever ever been
This dream has got me baffled, hey Joseph, tell me what it means

C'mon you know that kings ain't stupid
But I don't have a clue
So don't be cruel Joseph
You gotta help me now I beg of you

I was standing doing nothing in a field out of town -- I saw seven
beautiful ears of corn
They were ripe they were golden but you guessed it right
behind them were seven other ears -- tattered and torn
Then the bad corn ate the good corn man they came up right behind
yes they did
And Joseph here's the punchline it's really gonna blow your mind --
flip your lid
Because the bad corn was as bad as it had ever ever been
This dream has got me all shook up, treat me nice and tell me what it means

Hey hey Joseph won't you tell me what this crazy dream really means
