5. 3J – FAMILY MATTERS
The most mindboggling instance of COS has to be Family Matters. By season 4 the show decided to just completely erase youngest Winslow Child Judy from existence (sending her portrayer into a brief porn career) and then added Richie in season 2 to fill the cute little kid role. So why was it decided in Season 7 to introduce preteen orphan Jerry Jamal Jameson (referred to as 3J) and have the Winslows adopt him? Richie was pretty much the same age by now so any of the storylines they wanted to do could have been done with Richie and it would have cut down on the embarrassing “ghetto” slang that the character of 3J brought to the show. Besides no one cared about anyone on that show besides Urkel anyway so the introduction of 3J was just silly.
