Hungry?

Something bizzare happened last week at Texas A&M. While student tickets to the Cotton Bowl were being sold on campus, one coed cut to the front of the line and ate the roll call list. See here for details. Here's a quote:

"The list-eater was sold tickets, after cutting in line. Some witnesses said, after awhile the crowd started yelling 'eat your tickets.'"

What the heck is a roll call list?
