The picture below was taken as he was boarding the plane.
Halfway through the flight he figured out he was en route to Las Vegas, by overhearing a passenger.
Once in Vegas, he called the Las Vegas Sun, told them his story, and they put him in touch with the publicity agent at the El Rancho Vegas hotel, who gave him some money for his return trip. The airline made out his ticket to "Spaceman First-Class Bob Percy."
The pledges who did all this to Percy were said to be in store for "some sort of punishment." But I haven't been able to find out what that punishment was.
I was never a member of a fraternity, but I always thought it was the pledges who went through hazing rituals like this, not the rush chairman.
