>From C. Weibel, An Introduction to Homological Algebra, p. 11:

"The key tool in constructing the connecting homomorphism \partial
is our next result, the Snake Lemma. We will not print the proof in
these notes, because it is best done visually. In fact, a clear proof
is given by Jill Clayburgh at the beginning of the movie It's My Turn
(Rastar-Martin Elfand Studios, 1980)..."
