I was just playing around on webMD's symptom checker (c'mon- who hasn't?), trying to figure out why my ear has been hurting for the past few days, when I came across a medical condition called synesthesia.
Apparently, with some forms of the condition people can "taste" their words! They associate a certain taste with different words. There's one guy who tastes cold bacon when he says "jail".
Thoughts?
