Full House

This is the family show where it shows kids about morals and the right things to do during certain situations. It can also be comical and silly. 

Have you ever noticed their living arrangements? Uncle Jessie, Danny, and the three girls. They're all family. But then there's Joey Gladstone. He's not their family, so why is he there? 

It is suspected that he's there for a temporary place to live until he can get back on his feet, but he never leaves throughout the entire series.

The theory is that the reason Joey stayed there for so long was because the Tanner girls were actually his daughters, not Danny's, and he wanted to watch them grow up.

All three of the Tanner girls are blonde haired and blue eyed gals. However, Danny has brown hair with brown eyes and on the old tape, Pam was a blonde. 

It is possible for Danny and Pam to produce offspring that have these traits, but it's very rare as there is about a 1 in 16 chance of having a single blonde so the chances of all 3 being blonde is about 1 in 4,000. 

But someone who could improve these odds is none other than blonde haired, blue eyed Joey Gladstone, who conveniently stays there without being related to anyone.

Or is he, this would explain why he's sticking around, raising his children? 

I never thought of this before omfg.
