You'll never see this happen again.
Dragon Challenge's theoretical hourly ride capacity: 3500 riders/hr
Islands of Adventure's average daily opening: 10 hrs/day
Number of days since Islands of Adventure opening (as of Oct. 19, 2011): 4527 days
3500 riders/hr x 10 hrs/day x 4527 days/ever = 158,445,000
Each time you rode Dragon Challenge, you took a 1 in 150,000,000+ chance of having to get your eye surgically removed. Isn't math fun?
