Moonwalking Apollo astronauts had lots to accomplish in a short time. To keep them on track, each astronaut had a little book strapped to the cuff of their spacesuit. The book had reminders about the tasks they needed to finish in which order.
Sometimes, the checklist creators would add some humor. The reminder below relates to a high-energy snack bar the astronauts could nibble while they worked.

Apollo 16 moonwalker Charlie Duke said,
"That food stick was a thing that stuck inside the suit and it came up like this (on the right-hand side of the neck ring) and, when you were out on the surface, you could just reach over (with your teeth) and pull it up and chop off a piece. And it was really high-energy stuff."
