Where to start….? Pile them up off the front, or the back, or both; i.e. call the treble down to lead, then the second down to second's place and so on.
Reminds me of a wedding a few decades back. We were ringing call changes and the conductor was trying to call us round but the bells were drifting out of place quicker than he could call the changes. We must have stopped ringing eventually, somehow.
