Your most recent post reminds me of an episode of M*A*S*H, in which Hawkeye and Trapper are trying to disarm a bomb.
Henry is at a safe distance from them, reading aloud from instructions regarding the best way to do this.
As they near the most dangerous part, Henry's voice can be heard saying (something like) "Once you can see a red wire and a yellow wire, cut the yellow wire".
Hawkeye, sweating greatly, cuts it.
Henry continues: "But first, make sure they are both twisted around the lever on the left …"
The bomb goes off. Happily, it is filled with propaganda leaflets.
Do you get my point?
