These goddamn bastards right here. I have done a search of the most evil one, wintergreen, with no success. I feel that flavor was obviously discontinued because the bluish green mother f#ckers finally succeeded in choking its victim to actual death.
I stand witness to the attempt of one such ball that almost ended it for me. Circa 1964 I was standing at the reception area of Emma's Beauty Salon whilst my mother was getting her hair did. I'd already read all the latest on Liz and Dick, and was flipping through Emma's "hairdo of the month" desk calendar, when, fascinated by its unearthly color I unwrapped the wintergreen one and popped it in my mouth.
The flavor surprised, almost repulsed me, and the imp took the opportunity to slide down my throat and lodge there. Realizing I couldn't breath, my first thought was to not tell my mother, as then I'd be in trouble. Things were starting to go black when somehow I managed to use the last of the air in my lungs to gag it back up. It felt like my eyes were bugging out pretty good.
Seeing that no one had noticed, I examined it between my fingers briefly, then, well, waste not want not, put it back in my mouth.
Below is a bonus image of a typical hairstyle in said calendar....
