You can be a goody two-shoes 'till the end of your days
You can listen to them say crime never pays
You can follow every law and be the big black bat
But why would you want to?  Huh!

Where's the fun in that?
Where's the fun in that?

So, smile, darn ya, smile
Everybody loves to grin
Follow my lead, recite my creed
And smile, darn ya, smile

Don't listen to the dullets say that life is a bore
Those fuddy-duddies spoil my fun!
That's why I strive to eradicate gloom
It's from that itch I made the switch
And chose my nom de plume
The Joker!

There's the fun in that
Ha ha ha!
There's the fun it that

So, smile, darn ya, smile 
Everybody ought to laugh 
And so, with glee
I do decree.
Just smile, darn ya, smile

So, when living gets a little rough
And you find it hard to cope
I'm the gent with just the stuff
To fill you full of hope

Just smile, darn ya, smile
Everybody needs a clown
Now with one stroke, the final joke!
Just smile, darn ya

Smile, darn ya, smile 
Everybody loves to grin
Follow my lead, recite my creed
And smile
Ha!
Darn ya, smile

Ha ha ha!
I love it.
