I remember one time I went to Barbican Cinema One to see a Concert Staging (one of the Lost Musicals), and there were a couple of elderly gentlemen sitting next to me, I did not know them, but we got talking. And ended up talking about one particular performer who was sometimes in those shows and these two gentlemen were rather slagging off that particular lady's dress senss and hair style, so I said "Yes well I always think she looks like a Muppet". At which the two gentlemen appeared shocked and said "Ooooh better not tell her that". Yet I think my comment was compairing her style to The Muppets was rather more reasonable than some of the things they had been saying, especially given that the performer concerned happened to have worked with The Muppets.
