Sean passed his yawn to everyone in the freaking room just because he stayed out too late last night. It was like the fucking Voyage of the Yawn Spreader in there.

Don't even think about taking Jefferson's Public Administration class. It's just another Voyage of the Yawn Spreader. Everyone falls asleep within the first ten minutes.
