I can't believe this thread has reached two pages and no one has busted out a Sisko gif and a Sisko-like ITTTT'SSSS REEEEEALLLLLLLL!
There was this episode of "The Big Bang Theory"
where Rajesh says to Summer Glau something about her being in space when she starred in "Firefly"
and she asks him if he's one of those people who actually believed that. I assumed this was just some typical sitcom insult line, not a question based on a genuine belief that such people really exist.
