Say you were dragged before the king...

...thousands of years ago...and he told you to entertain him or else...off with your head!

What could you do?

No props:

Sing
Dance
Tell a story
Tell some jokes
Acrobatics

Throw in a prop and you could also:

Play Music
Juggle
Do magic tricks
Create some art

Add a few people and you could:

Put on a play
Stage an athletic contest
Stage a talent contest

Not much has changed in the entertainment field since...the start of humanity.

Wonder why?
