Make 'em laugh

Though the world is so full of a number things,
I know we should all be as happy as
But are we?
No, definitely no, positively no.
Decidedly no. Mm mm.
Short people have long faces and
Long people have short faces.
Big people have little humor
And little people have no humor at all!
And in the words of that immortal buddy
Samuel J. Snodgrass, as he was about to be lead
To the guillotine:
Make 'em laugh
Make 'em laugh
Don't you know everyone wants to laugh?
(Ha ha!)
My dad said "Be an actor, my son
But be a comical one
They'll be standing in lines
For those old honky tonk monkeyshines"
