I found myself oddly riveted to this fella’s voice reading the description of how to tell the difference between corns (or I should say, “cahns”) and callouses from WebMD.  He’s got a really great, authentic Maine accent and I never really gave much thought to corns and callouses or what causes them. After all, I’m a DJ. Your hands don’t get very rough cueing up CDs and pushing buttons. This is a wicked funny way to get educated on the subject. I bet you end up listening to the whole gommy thing and figurin' out what that thing is on your foot.
