In-Jokes of the Disciples

Aside from what is recorded in the Gospels, it might be nice if there were also a record of the silly and funny things that happened during their mission. They would be the stories the disciples told each other, the ones beginning with, "Remember..." and ending in laughter as they did. They are the things a person might not understand if he were not there at the time, and while not recorded I am sure they happened. Unless there was silliness and fun it would have been an awfully ponderous trip.
