The postman came on a Monday
And put a letter in the letterbox
Put a letter in the letterbox
The postman came on a Tuesday
And put a letter
And a frog in the letterbox
Put a letter and a frog in the letterbox
The postman came on a Wednesday
And put a letter
And a frog
And a mouse in the letterbox
Put a letter and a frog
And a mouse in the letterbox
The postman came on a Thursday
And put a letter
And a frog
And a mouse
And a spider in the letterbox
Put a letter and a frog and a mouse
And a spider in the letterbox
The postman came on a Friday
And put a letter
And a frog
And a mouse
And a spider
And a snail in the letterbox
Put a letter and a frog and a mouse
And a spider and a snail in the letterbox
The postman never ever came again
He was fired
And he was told
That he was a very silly boy
