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.
Thanks for the information i had no idea.  Maybe one day i will go see a clown show and face my fears. 
Yes, and though you usually find clowns as part of circuses, there are some that can become their own solo act.  A great way to confront it.
I bet they would make much more money doing it solo 
Joseph Grimaldi played one of the first mainstream clowns back in the day.  He was the originator of the white make up they use.
