I saw this and my jaw dropped

Be a clown,
Be a clown,
All the world loves a clown
Act the fool, play the calf
And you’ll always have the last laugh,
Wear the cap and the bells
And you’ll rate with all the great swells,
If you become a doctor, folks’ll face you with dread,
If you become a dentist, they’ll be glad when you’re dead,
You’ll get a bigger hand if you can stand on your head.
Be a clown, be a clown, be a clown!
