My dad tells me that he took us to a pantomime when I was very very small - panto being a sort of English phenomenon. There's traditionally a part of the show where they'll invite kids up on the stage to interact with the show. I was too young to remember this but my dad says that I was running up onstage before they even asked us.

I like actors that are good with pantomime and that can transmit a lot by their presence and attitude more than through their dialogue.
