Back in the day, Chicklets were included with each C-ration meal.
C-rats have morphed into MREs, and I believe Chicklets survived the transition.
Back in the early 80’s a brother of mine was taking gym class in high school and at the beginning of the class they would go to the locker room and change into their gym clothes, leaving their other clothes in the locker room. There were no lockers in the “locker room” to store your clothes so you placed them in your own pile when changing.
The gym teacher pulled the boys in first day of class and said I hate a thief, if anything gets stolen in here I will let the others in the class deal with the thief and I will see nothing, understand. A week or two passes and nothing happens then things start disappearing out of the clothes in the locker room, money, gum, candy etc... No one could catch the thief in the act. They eventually hit my brothers clothes and stole his new pack of bubble gum.
He decides to retaliate on the unknown culprit by buying a pack of Chicklets and a pack of laxative Feenamint gum and putting the Feenamint in the Chicklet package and leaving it in his clothes. Sure enough it was taken and the next day the class noticed one of the other classmates out. He comes back and he had diarrhea. So a couple of others watch this clod and sure enough Feenamint boy strikes again but is seen. The class counseled him in the error of his ways and there were no more thefts.
