Oh, I kinda liked it, pretty good for math jokes.

Here's one:
A mathematics professor was lecturing
to a class of students. As he wrote something
on the board, he said to the class
?Of course, this is immediately obvious.?
Upon seeing the blank stares of the students,
he turned back to contemplate
what he had just written. He began to
pace back and forth, deep in thought.
After about 10 minutes, just as the silence
was beginning to become uncomfortable,
he brightened, turned to the
class and said, ?Yes, it IS obvious.?
