Can't tell your Capulets from your Montagues without a program

I vividly remember a Bugs Bunny cartoon where Bugs is hawking programs at a Shakespeare play and saying “Programs, programs. Getcher programs. Can’t tell your Montagues from your Capulets without a program.”

My googling is not turning up this line. Did I imagine it?

Well, not exactly. It’s actually from Romeo and Juliet, by W. Shakespeare.

Act V, Scene LXVI.

Some googling around suggests the line might be “You can’t tell a knight from a day without a program”, which would imply maybe it’s in this one (which I haven’t watched yet).

I dunno, doesn’t sound like Bugs to tell you the truth. Sounds more like an Animaniacs type of gag. But I’m guessing.
