Why are we so serious?

Why don't we just laugh
And enjoy the ride?

We're all here for a reason

So let's just have some fun
And live our lives today

Life's not always what we planned
But it's still worth fighting for
So let's just take it easy
And enjoy the journey along the way

Life's a journey worth taking
With ups and downs along the way
So let's just embrace it
And live our lives today

Why so serious? Let's just have fun
