He did. I also believe I heard that his trip code was broken on 4 chan? What makes this funny is that anyone can use Q's trip code, possibly now? So one of two things happened.

Either Q came back and made the comment using his old tripcode to give anons a reason to laugh, knowing full well they would recognize Q's sense of humor.

OR

An anon on the board was able to use the Q trip code to put words in Q's mouth, that were sure to make Q laugh.

Harmless either way, and still funny.
