While we're on the SUBJECT,
why did you guys break up, anyway?
The Big Bang Theory Season 4, Episode 4
so it's probably a good SUBJECT
to avoid if at all possible.
Game of Thrones Season 6, Episode 6
And if he brings it up,
change the SUBJECT
The Big Bang Theory Season 12, Episode 15
...from the SUBJECT matter.
The Big Bang Theory Season 1, Episode 17
DR. KOOTHRAPPALI:
Okay, we're getting off the SUBJECT.
The Big Bang Theory Season 4, Episode 20
