Saturday Night Live (1975)

"Nerds & The Nurse," February 24, 1979 Gilda Radner's Lisa Loopner and Bill Murray's Todd DiLaMuca are the snorting, noogie-trading teenage nerds who are secretly devoted to each other, with Jane Curtin as Lisa's mother, Enid. Radner's laugh and the affection under Murray's teasing make these sketches sweeter than their reputation, and this one, with host Kate Jackson, brings a visitor into the Loopner living room. A good pick if you know Radner mainly from her Weekend Update characters.
