Getting sequences right

The M*A*S*H episode “The Army-Navy Game” illustrates the importance of getting sequences right in technical writing. Blake and Trapper John are trying to defuse a bomb:

LT. COL. HENRY BLAKE (reading instructions)
And carefully cut the wires leading to the clockwork fuse at the head.

TRAPPER JOHN (cuts the wires)

LT. COL. HENRY BLAKE
But first, remove the fuse.
