Very ambitious this close to Christmas!
A lot of your jokes are going to be dependent on the Dame. Make sure they pick someone very confident to ad-lib and improvise because that’s the most important part of their role (arguably the most important part of the panto).
Cinderella is quite a difficult one, because usually it requires two dames for the ugly sisters, and they will have to be really really good together.
It’s hard for us to suggest puns and innuendo because it’s dependent on the context. Ones I remember sticking out are from the scenes where characters (usually the clown and the dame) were planning to sing a song. The song suggestions were usually along the lines of:
‘She was only a surgeon’s daughter, but she certainly knew how to operate’
‘She was only the fisherman’s daughter but she knew how to handle a rod’
Good luck with it, sounds like fun.
