Who is this man?

My parents take the whole family to the circus in Topeka every February.  I think my Dad is going a little crazy (but don't tell him that). 

He had his picture taken with the clowns (strange) so that he could ask people "How many clowns are in this picture?" as he chuckles to himself.

My reply "Three.  But I'm on the fence with the guy on the left."

Makes me want to sing "One of these things is not like the other, one of these things just doesn't belong".

My Dad is his own comedian.  He literally cracks himself up. 

Makes me laugh, which doesn't happen often enough.  (Maybe I'm the crazy one?) 
You don't have to answer that.  :)
