I also hate the "Lincoln is adopted" theory so I am glad there is finally something Austin and I both agree on.

Also I am not sure if Clyde is actually "adopted". I think he is Harold's (I think it's Harold, I cannot tell the two apart) biological kid because they are both African-American and they probably had a surrogate carry the baby. I think this because I have a theory that because we saw this character who IMO looks an awful lot like Clyde in "Patching Things Up", it could be her stepsister because it could be the surrogate's actual child if she chose to have children of her own and since it would be technically her egg and Harold's sperm, they would be related. But that is just a theory that I made up that I think is pretty cool and would make for a decent episode of the show.
