Look on the bright side of life (all things dull and ugly) Monty Python

Some things in life are bad
They can really make you mad
Other things just make you swear and curse
When you're chewing 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
[whistle]
Always look on the light side of life
[whistle]

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
And...

Always look on the bright side of life
[whistle]
Always look on the right side of life
[whistle]
