Monty Python's Life of Brian

Absolute classic and a must watch.

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...

Life's a piece of shit,
When you look at it.
Life's a laugh and death's a joke, it's true.
You'll see it's all a show,
Keep 'em laughing as you go.
Just remember that the last laugh is on you.
