Always found the term funny used in this context.
This post is to simply to recount my experience this morning with the GMAT.
I had a an early morning appointment at 8:30 AM. The test center was far so I left @ 7:00 AM to reach at 8:00 AM. Unfortunately, I had a restlessness night and did not sleep too well - don't know why. The effects were going to manifest themselves later. The center was closed even at 8 AM and almost all the test takers were already present. The proctors arrived soon enough and let each one of us in one after another with the usual routine.
