lecture u
When the average audience assembles to be given a lecture the back couple of rows will fill up and the remaining students will only sit along the sides of the front rows creating a U shaped audience with no one sitting in the middle. This presents a challenge to the late student - his three options are to; budge one of the side sitters into the middle, go around the front and climb into the U or the bravest amtept to climb over the back filled rows and into the U.
I can't believe I was late for my lecture; the lecture u had already formed.
