From episode #131, The Case of the Travelling Treasure

After finding the victim, the Lieutenant exits the cabin
and has a few words with the Captain of the boat...

Note that his top row of ribbons are unhooked on one
side and are hanging down over the bottom row.


During the conversation, the camera cuts away for a
short reaction shot and, when it returns, the ribbons
are magically rehooked and in their proper place.
