Fred Flintstone
"The Simpsons" referenced "The Flintstones" in several episodes. In the episode "Homer's Night Out", Homer's local convenience store clerk, Apu, remarks "You look familiar, sir. Are you on the television or something?", to which Homer replies "Sorry, buddy, you've got me confused with Fred Flintstone." During the couch gag of the opening credits of the episode "Kamp Krusty", the Simpson family arrive home to find the Flintstone family already sitting on their couch. The same couch gag was reused in syndicated episodes of "The Itchy &amp; Scratchy &amp; Poochie Show", when "The Simpsons" overtook "The Flintstones" as the longest-running animated series. In "Lady Bouvier's Lover", Homer's boss, Mr. Burns, appears at the family's house and says "Why, it's Fred Flintstone (referring to Homer) and his lovely wife, Wilma! (Marge) Oh, and this must be little Pebbles! (Maggie) Mind if I come in? I brought chocolates." Homer responds by saying "Yabba-dabba-doo!" The opening of "Marge vs. the Monorail" depicts Homer leaving work in a similar way to Fred Flintstone in the opening of "The Flintstones", during which he sings his own version of the latter's opening theme only to slam into a chestnut tree.
