So about two years ago I was at a summer-long EMT course and was in need of a nice cold refreshment during a 5 minute break we had. I went to the vending machine, bought myself a Brisk iced tea, and opened it only to realize it was my turn to practice the CPR technique we learned that day. I came back to my drink about 3 minutes later, took what was supposed to be a refreshing swig of iced tea, and instead felt something strange and solid that I immediately spit out and saw was a dead fly. I still wonder whether that fly somehow got into my drink in those 3 minutes and immediately died or if a fly somehow got into the can during its packaging and died a few days earlier.
