What was the most disgusting thing you've tasted?

Lately it seems that a lot of people are getting sick with sore throats. Perhaps it's because here in the US we've moved into the colder weather with winter approaching. Or perhaps it's just that time of year for cold and flu bugs to be running around.

Either way, it got me to thinking about the thread over at OtakuBoards where the question was asked: What was the most disgusting thing you've tasted? Of course you had the standard foods and other odd things, but medicines such as cough syrup kept popping up in the thread.

So you tell me, which is worse, some random odd food or some medicine that you've had to take in the past when you were sick. So far, the worse thing I've had was some medicine. I swear, it's like they want you to not take your meds and stay sick! =P That stuff is just vile!
