Captain 11 was a popular after-school children's program for over 40 years on KELO-TV, broadcast on channel 11 from Sioux Falls, South Dakota. Station weatherman Dave Dedrick donned a yellow-trimmed blue pilot uniform with hat and daily became the jolly host of the show. The show primarily played cartoons and other children's fare, and featured the Captain having all the kids introduce themselves on the air, guessing to win the toy chest, and children with birthdays working the Captain's control panel of lights and switches. The show ended with the Captain playing the "freezeberg" game with the children, having them: Face the camera and wave one hand: then wave both hands: followed by wave both hands and one foot then wave both hands and both feet which usually resulted in most of the kids jumping up and down while facing the camera. Finally, the Captain would tell them to "freeze", not moving a muscle as the camera panned over the crowd of kids attempting to remain still.

Captain 11's Showboat was a locally produced children's program, based in St. Louis, Missouri, airing on KPLR-TV, Channel 11 during the late-afternoon hours, starting in May 1959, and ending in August 1968. Captain 11, named after the channel, was portrayed by longtime St. Louis radio personality Harry Fender. The program was best known for airing Three Stooges shorts to viewers in the St. Louis area. After the series ended in 1968, the Three Stooges shorts continued to air on the station, although the shorts currently air occasionally. Harry Fender played Captain 11. Mr. Fender was a former performer for Florenz Ziegfeld. He then returned to St. Louis and became a policeman. Mr. Fender was a semi-regular on Jack Carney's radio program on KMOX radio. Mr. Fender claimed many times that when Florenz Ziegfeld was creating the musical version of Show Boat that Ziegfeld had Fender in mind to play Gaylord Ravenal.
