Evolgen presents a series of hilarious classifications of the kind of people who come to listen to talks and seminars in grad school:

The rookie: The pre-schooler knows seminar time is nap time. The rookie is an undergrad or first-year grad student who’s new to the whole departmental seminar thing. He’s overworked, he undersleeps, and he’s sitting in the middle of the room. He nods off throughout the seminar, and everyone’s looking at him. Wake up boy, and get your act together. And next time, sit in the back of the room with the pre-schooler.

Do follow the comments section as well! Sample this from there:

How about the opposite of the Master - the senior faculty member who habitually sleeps through the entire seminar, and then asks a question that was covered on the second slide.

Haha, who says grad school ain’t fun? :D
