For those of you out there who are still unsure as to what a "picture clown" is, meet Mr. Keith Crary. This is a photo of Keith from the 1985 Great Circus Parade in Milwaukee, WI.
Now Keith is not going to be taking any slaps, doing any falls or taking a pie in the face in this outfit but you can't deny that he looks like a million bucks in it. His picture in the paper or featured on a circus poster is guaranteed to get noticed.
That is a "picture clown".
It doesn't mean that you can't be funny, it simply means that you are a great looking clown.
