A lot of people see clowns as physically comedic, but I've always found them physically intimidating.
Same here i actually find them to be very scary in my opinion 
I think since a lot of cultures have their own styles and variations in costumes when it comes to clowns, some may be creepier than others.
Yeah thats very true.  Is there anything else you can tell me about clowns?
The way they entertain is usually from a distance by design, which is especially suited for large audiences.  The farther away the better.
