Lunch today... tabasco bottle won't flow! We pass it around the table, everyone tries something to free it. Toothpick - nope. Shaking while capped - nope. Tap, tilt, rack - nope. Finally comes to me, I uncap and peer into the hole just as "ploot!" a bubble moves internally and a shot of tabasco fires right into my eye. Son of a freaking mojo did it hurt - instant blindness, instant pain. Glad I'd spotted the men's room on the way in. Took a good five solid minues of water rinsing before I could head back to the table.
Lesson learned. Treat every tabasco bottle as if it were loaded.
[Edit: Hours later now, I am still feeling it.]
