I honestly thought, at first, that Dave was Michael's husband. Especially when I first saw the cruise pics of them laying on top of each other.
And that he was the "normal" one of the two.
While Michael would be squealing about Mickey and talking about "waves of Disney," Dave would just usually nod, smile, be quiet, and be in the background.
(of course, this was before he got more into vlogging with that "Dave Kay Flow"...and "The Gem" and "Havoc" and all the weird ass
tit like that)
When I found out they were actually brothers, I couldn't believe it.
(I also couldn't believe that Dave graduated from USC with a degree in communications, and looked and acted normal in his college videos / pics...but that's another story)
