Short about a clown who kills the mayor (?)

Back in the 1980s this short was on cable TV all the time as a filler. What is it and who is in it?

I remember it as a B&W. There is no spoken dialog, but there is narration. X the clown comes to this small European village. He’s wacky, but over time everyone comes to love him. One day he shows up at the mayor’s (?) office. Oh, it’s X the clown. How wacky he is. What, you want to tie my hands to the chair? Sure, I have nothing to fear from you …. And then POW! The clown kills him and goes off.
