Do what crier did — sound familiar? (4,1,4)
I believe the answer is:
ring a bell
This clue is a double definition.
'do what crier did' is the first definition.
(as in a town crier)
'sound familiar?' is the second definition.
(I've seen this before)
(Other definitions for ring a bell that I've seen before include "Beginning to arouse a memory" , "to remind one of something" , "Campanologist might" , "What door-to-door salesman's wont to do" , "start to arouse memory" .)
