If you think this is an easy question to answer, guess again. Wide boundaries outline the category of "Single Dads" on TV. After devoting an embarrassing amount of time studying the phenomenon, I've come up with four cardinal rules to identify TV Single Dads:snip
Precocious Kids - All the children of Single Dads are bubbling vats of adult vocabularies. Even the Olsen Twins on Full House have the elocutive range of third-year law students. Single Dad's Kids (SDK's)can size up their Dads' new girlfriends (who usually only last for one episode) and find the newcomers' mortal weaknesses. Under no circumstances do any SDK's get into fights with siblings where blood spillage will ensue. For a certain sighting of the element of precociousness (precocity?), watch any episode of Nanny and the Professor. Hey, Jonny Quest illustrates the concept pretty good, too.The menu on the left has some interesting links as well (check out the 80s page)
