Clara is a female person, with peculiar parents who gave her a middle name ridiculously similar to her last name.
On further research, I also note she is a fictional character in a TV series called Dr Who, which every other person seems to be talking about these days.
Dr Who obviously loves Clara.
But due to her strange middle name he struggles to cope.
Which is why he is called Doctor Who.
