Are You Sure They're Twins?

I think it's like he's he has a twin brother that works at a optometry place. I go to the same optometrist and he tells me that story every time I go in about how Dan Harmon was so relieved he wasn't racist. We were like leaping up and down like as if one of us won the lottery and me going like I thought I was racist and he's like you're not racist and it was like funny.
