Always look on the bright side of life
Written by NotFatPolarBear
Some things in life are bad
They can really make you mad
Other things just make you swear and curse
When you're chewing 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
Ju
