It’s not so common anymore, but most of us have seen a character doing a stylized Egyptian dance. That dance is derived from the sand dance, done by a trio of music hall performers. Here is the Wikipedia intro to Wilson and Keppel and Betty.
Wilson, Keppel and Betty were a popular British music hall act in the middle decades of the 20th century who capitalised on the trend for Egyptian imagery following the discovery of the tomb of Tutankhamun. Their stage act, called the “sand dance”, was a parody of Egyptian postures, combined with references to Arabic costume. The lithe and extremely lanky Wilson and Keppel, who wore long mustaches and make up to emphasize the sharp angularity of the features so as to appear almost identical, would demonstrate their impressive suppleness in adopting wild gestures and dancing in identical “stereo” movements (using gestures vaguely reminiscent of Egyptian wall paintings), while Betty watched their antics. Theirs was a soft-shoe routine performed on a layer of sand spread on the stage to create a rhythmic scratching with their shuffling feet. The act was usually performed to the familiar Egyptian Ballet (1875), by Alexandre Luigini.
And here is a video of them doing the dance.
