Nola Rae is a mime artist, clown, and one of the funniest women on the stage. Tonight she recreates some of her most bizarre and poignant characters - the failed ballerina, the unhappy hooker and, unforgettably, Nola's Nasty Mime. Michael Dean makes a valiant attempt to interview her.

Yesterday, Tomorrow and You
James Burke concludes this look at 2 000 years of human ingenuity by turning from the past to the present. This week he shows how the results of all those amazing connections in the past are all around us now - without our realising it. Do we know enough to predict how they will connect and bring change for us? Can we control it - and do we care?

Portrait of a Poison
Dioxin is the most deadly chemical man has ever made. A few specks of it would kill you. Unlike other poisons, dioxin is of no use to anybody. It is merely a by-product in the manufacture of certain herbicides, such as the defoliant 'Agent Orange used by the Americans in Vietnam. Dioxin brought disaster to Seveso, Italy, when a toxic cloud polluted the town; dioxin caused disease in 90 British workmen in Derbyshire. In animals, dioxin causes cancer, abortions and birth defects. What effect is it having on man?
Evidence is mounting - from Vietnamese peasants and US army veterans, from mothers in Oregon, from over 2,000 accident victims. Have scientists lagged behind events? How many other chemical poisons surround us, so far undetected?
