Slim wore custom made boots by Texas boot designer Charlie Dunn, that cost up to $3000 a pair.
Slim was a featured performer in the Calgary Stampede, the world's largest annual rodeo in Alberta, Canada, during the 1950s.
Slim sang and recorded the country song "Desperadoes Waiting On A Train", as well as singing backing vocals for the soundtrack album of Honeysuckle Rose (1980), which he also acted in.
Slim was never shown the entire script for Dr. Strangelove when he filmed his scenes and didn't know it was to be a comedy, which director Stanley Kubrick deliberately did to make his scenes all the more ironic in the context of the movie.
Slim allowed his voice to be used for the character of Rube Dugan in the Silver Dollar City theme park attraction, "Rube Dugan's Diving Bell," starting in 1978. This ride would take guests on an underwater tour of Lake Silver, in Branson, Missouri, and was in operation until 1984.
Slim was the highest-paid rodeo clown in the business during his rodeo career.
Slim started performing in rodeos when he was 12 years old.
Slim was inducted into the Rodeo Historical Society's Hall of Fame in 1986.
Slim had three children, Darryle Ann, Thom, and Margaret Lou.
When Slim showed up on the set of "Dr. Strangelove" (1964) in England, the British actors thought he was method acting, being dressed and talking with the cowboy accent he had, not realizing that it was his real self they were seeing and hearing.
Slim was inducted into the Rodeo Hall Of Fame in 2005.
Slim's rodeo jobs included bullfighter, rodeo clown, bareback bronco rider, and saddle bronc rider.
Slim was hired for the part of Major Kong in "Doctor Strangelove" (1964) after Peter Sellers broke his leg, in addition to his being unable to mimic a Texas accent as well. He was the third choice, after John Wayne and Dan Blocker refused the part, and director Stanley Kubrick remembered his work from "One Eyed Jacks." (1961)
Slim was inducted into the Western Performers' Hall of Fame in 1982.
Slim's brother was an actor also, and went under the name of Easy Pickens.
Slim was originally offered the part of Dick Hallorann in "The Shining" (1980) but refused, saying that working with director Stanley Kubrick before on "Dr. Strangelove" (1964) was too strenuous. He later changed his mind, saying he would do it if Kubrick would be required by contract to shoot his scenes in 100 takes or less. Kubrick's penchant for shooting scenes hundreds of times led to this stipulation, but Kubrick refused and cast Scatman Crothers in his place instead.
Slim's line "Shoot, a fella could have a pretty good weekend in *Vegas* with all that stuff" in "Dr. Strangelove" (1964) was re-dubbed from his originally saying "Dallas." President Kennedy was assassinated shortly before the film was released and the line was changed to avoid offending audiences.
Slim said he got his stage name from someone who told him that working in the rodeo for a living would be "slim pickings."
Slim was an excellent horse rider by the time he was 4 years old.
