Reference for Kiddushin 32:13
לא אידי ואידי דנפקא לה בסימנין ולא קשיא הא דאיתיה לאב הא דליתיה לאב
And should you reply: He teaches that which is fixed, but not that which is not fixed - but what of 'signs', which are not fixed, and which he nevertheless teaches? And should you answer: Here too, it is as R'Safra - but there is the master's death! This refutation of Resh Lakish is indeed a refutation.
