Siegel was teaching junior high in his hometown of Minneapolis before turning his back on dispensing education, in favor of receiving it as one of the 1,700 students to pratfall through the doors of Ringling Bros. and Barnum & Bailey Clown College between 1968 and 1997, earning a spot in their touring show.

There he was fortunate enough to study under the late, great Verne Langdon who “besides teaching us clown makeup and helping develop our characters. He taught us basic prosthetics – he had recently been on the original Planet of the Apes [1968] with John Chambers. I learned how to take the casting of my nose, do sculptures and molds and make my own rubber clown nose. Verne liked my work. And I enjoyed doing it. And we stayed in touch."
