of mine I used to work with is a former Marine.
We were talking one day, and by some cosmic force, the topic of canker sores came up. He told me that when he was in the Marines, a friend had told him that one of the best ways to get rid of a canker sore was ear wax. My friend was reluctant to try it, but did anyway. Apparently the next day, the canker sore was damn near gone.
Impressive, but it would take a lot more than a canker sore to get me to chew on ear wax.
