Got hit in the eyeball by a bug last week, and this week I was innocently hammering down the road and took a bug clear down the esophagus. I almost wiped out from the coughing and gagging that ensued. Come to think of it, it may have been a bird, not a bug... thing felt huge. Maybe it was a hawk.
I guess the good news is that it made it well past any taste receptors before I knew it.
