Pinto Colvig was the voice of Bozo the Clown on the 1946 record album that introduced Bozo to the children of the world. The album came with an illustrated read-along book (the first of its kind!) and stayed on Billboard's Best Selling Children's Records Chart for an amazing 200 weeks! Colvig also played Bozo on the first version of the TV show, Bozo's Circus, which debuted on KTTV in Los Angeles in 1949. In 1956, Larry Harmon bought the rights to the Bozo franchise and sold local versions of the show to multiple markets across the U.S. By 1959, he had 100 Bozos in the United States, plus clowns in Germany, France, and Japan.

Among some Roman Catholics, Saint Jude is venerated as the "patron saint of lost causes". This practice stems from the belief that few Christians invoked him for misplaced fear of praying to Christ's betrayer, the similarly named Judas Iscariot. The ignored Jude thus supposedly became quite eager to assist anyone who sought his help.
