Some things in life are bad
they can really make you mad
Other things just make you swear and curse
When you're chewin' on life's gristle,
don't grumble give a whistle
And this'll help things turn out for the best

And always look on the bright side of life
Always look on the light side of life

If life seems jolly rotten
there's something you've forgotten
And that's to laugh and smile and dance and sing
When you're feeling in the dumps
don't be silly chumps
Just purse your lips and whistle, that's the thing...


(Monty Python - Life of Brian)
