Ralph Crown mentions in this answer that a particular line in the play Hamlet could be interpreted as Hamlet breaking the fourth wall, and implies that this is common in Shakespeare plays:
Another [interpretation] is that Hamlet, like several other characters in Shakespeare, is aware of being a fictional construct.
I'm curious about how widespread this phenomenon actually is, especially if we exclude things like the "Chorus" or "Prologue" in plays such as Romeo and Juliet or The Winter's Tale, and also exclude lines such as the one in Hamlet which could be interpreted as fourth-wall-breaking but could also be interpreted in other, non-immersion-breaking ways. I realise that there's a lot of ambiguity and double meanings in Shakespeare, but some things leave little room for doubt.
How many of Shakespeare's actual theatrical characters have lines which are fairly unambiguously breaking the fourth wall?
