The dean of Engineering had once walked into a class, and said
"Good Morning." The whole class chorused "Good Morning".
"Hi, you are freshmen aren't you?" he asked.
One student bolder than the others asked him how he knew.
"Well," he said. "When I say 'Good Morning' to a class, if they are
freshmen they say 'Good Morning' too. If they are sophomores, they
quietly fold their papers away, and look at me. A class of Juniors
will look at me over the top of their papers, and then get back to
them. A class of Seniors will ignore my greeting, and keep reading
the papers. When I say 'Good Morning' to a class of graduate students,
they write it down.

because they are so big and varied, but I had this one lying around...}
