GreshamH said:The prefix "coulro-" may be derived from an Ancient Greek word meaning "stilt-walker",[nb 1] although the concept of a clown as a figure of fun was unknown in classical Greek culture.[5]
I did read that. Even though the etymology doesn't make all that much sense, we are still using it to refer to clowns in some way so I figured I try to make a cheap joke by adding ichthy to it.
