It is obvious the only correct answer is, of course, the old 'sad hobo' clown.

He is old and sad but he is also quite spry and lively and must be doing something right. Good times and bad the hobo clown lives on the border of town, lives on the fat of the land, does odd jobs as needed, survives ,and with his bindle and stick he gets on down the road. The sad hobo clown is a survivor.

The alien clown is no good. I'm not an alien, illegal or otherwise, so I don't qualify. Ditto with the zombie clown.
