Known for his humor, particularly about his undistinguished playing career, Uecker actually became much better known after he retired from playing. He made some 100 guest appearances on Johnny Carson's "Tonight Show". During one "Tonight Show" appearance, Carson asked him what the biggest thrill of his professional baseball career was and with his typical dry wit Uecker replied, "Watching a fan fall out of the upper deck in Philadelphia; the crowd booed." Most of his wisecracks poked fun at himself. He once joked that after he hit a grand slam off pitcher Ron Herbel, "When his manager came out to get him, he was bringing Herbel's suitcase." On another occasion, he quipped, "Sporting goods companies would pay me "not" to endorse their products." On his later acting career, he commented, "Even when I played baseball, I was acting." Even when he was announcing games, he often said some outlandish things, like during a particularly bad game the Brewers were playing in, where he reportedly said, "A couple of grand-slammys and the Brewers are right back in it."
