I have just discovered that one of my favourite Sesame Street sketches is widely available to watch online.
Sometimes called Caveperson Days, sometimes Caveman Days, the Sesame Street team have a lot of fun with furs, ug-speak and anachronisms. So suspend your archaeological knowledge, and go and enjoy Bert and Ernie bickering in cave-speak.
Plus you learn how to cross the street safely.
