Sherlock: Hey John. I found your old report card from high school. You were horrible at math, you know?

John: Oh well yes. I've always sucked in Math class.

Sherlock: John check your grammer.  It is "at math" not "in".

John: No, it is "in" ;)

Sherlock: wait...

Sherlock: John did you just...?

John: I have no idea what you are talking about ;)
