Sheldon: I'd like to start this episode by apologizing on behalf of Dr. Fowler, who made the wild claim last week that there was no national tricolored flag with a purple stripe, when, in fact, the Estonian governorate inside the Russian Empire had a purple stripe on their flag from 1721 to 1917. See? Right there in the middle.
Amy: And I'd like to apologize on behalf of Dr. Cooper for having his zipper down for the entire segment on the flags of East Africa.
Sheldon: Sorry, Tanzania, you deserve better.
