Academic building at Virginia Tech. The first three floors are mostly classrooms (although there are a couple computer labs in the first floor/basement, as well as a huge lecture hall/auditorium, McBryde 100), the fourth and fifth floors host the math department, and the sixth floor is home to the computer science department.

One late-night discussion with a couple of my friends centered around the best possible way to destroy the fourth and fifth floors with minimal damage to the sixth. I don't mind the CS dept., but the mathematics department has done its level best to kill me since I arrived in 1997.
