I don't know why I put this on the list. Where can I possibly find definitive proof of whether or not Zaccheus was a little person. There is none. It's not like we can go look at his death certificate or anything like that. I'm an idiot.
I did find some interesting information about size. It seems that every generation of human beings seems to be getting larger. This means that way back in Jesus's time people were probably on average 5 foot or shorter. This means that if Zaccheus were referred to as a "wee" man in the Bible, he must've been really short. This is the circumstantial evidence that I'm using to determine that Zaccheus was a little person.
