I was watching the local ABC affiliate yesterday morning when they did a piece on the Ringling Bros. Circus that is in town (Nashville). One of the clowns was wearing a kilt. Well...it was more of a "costume" kilt. It was gathered rather than pleated. He was a clown after all. Ringling Bros. currently has 3 shows traveling. This shown is know as the 135th edition or the Red Tour, starring Bello. The kilted clown's name was Luke. He spoke with a thick Scottish accent, though his clown bio has him coming from South Dakota.

Unfortunately I can't make it this year. If this tour is coming to a city near you
you just might see Luke, the kilted clown.
