Casting directors are paid billions of dollars* to cast movies and TV shows, and sure, we understand with the sitcoms you're going for the funny and talented thing.**
But if people are supposed to be genetically related, how do you explain the following family portraits?:



Okay, look: aside from looking nothing like each other, Mark, Randy, and Brad Taylor didn't look anything like their parents, either. And even when Jonathan Taylor Thomas allegedly went through puberty, he was still a solid three feet shorter than Tim Allen. JTT doesn't even look related to
humans, much less typical midwestern families.
And since DJ, Stephanie, and Michelle Tanner all look nothing like Danny, are we to assume that, despite also looking nothing like each other, they all look like their dead mom, who we only ever see once for like five seconds in a "home video"??
And what the hell is up with "Family Matters"? Why is Eddie Winslow so tall? How come Laura looks adopted?? Wasn't there another sister??? What happened to her? Did she die? Did she will herself out of existence? Does sitcom genetics allow for this, like when the mom on "Fresh Prince" suddenly changed her entire DNA makeup?
Bullshit.
At least Kirk Cameron sort of looked like Alan Thicke, albeit with a voice that was like three octaves higher.
*probably
**which means "House of Payne", "Two And A Half Men", and "According to Jim" are automatically out of excuses.
