Other running gags include Fred fumbling through several pairs of eyeglasses before he can find the right pair, threatening to punch somebody by indicating his fist and saying, "How'd you like one across your lips?," telling someone "My name is Fred G. Sanford" with the G standing for various words from episode to episode, and the fact that Fred is a big fan of singer Lena Horne; she actually makes a guest appearance as herself in episode "A Visit From Lena Horne" 2/16 in 1973.
