The messy kitchen, decorating or similar scene in which (usually two and almost always male) actors get covered in pie, gunge or messy foodstuffs is a hallowed tradition of panto. (As a young man in an amateur drama group I enjoyed doing it myself).
However in recent pantos I've seen, the slosh act has been disappointing or even absent. Cambridge Arts Theatre is a notable exception with a fine tradition of messy slapstick.

Why is the slosh act endangered? Is it the expense of pie mix and gunge powder, which we all know can add up for a good session. Or are actors these days just not willing to get messy?

I would love to do this kind of slosh with some one

Clean up
Lack of willing victims
Expense
Differing tastes in plays
Theatre not wanting any potential damages or injuries.

Could be any number of reasons. Good to see Cambridge still managing something, not that I particularly want to see a panto.

Been the victim a few times now - usually when I go to watch panto !

That someone is me, John

Oh yes you do
