While all that was at the height of its hilarity I overheard the following conversation between the guy dressed as Osama Bin Laden and Miss Piggy.
Osama (to Miss Piggy) Your problem is when you take your mask off you are still ugly.
Miss Piggy ( a very big girl, drawing back her fist) What?
Osama (cringing) Sorry I should not have said you were ugly.
Miss Piggy (smiling) That's OK. I thought you said I was from Dudley.
Both resume singing and dancing.
It was that sort of day. Magical.
