Uncanny X-Men #372 (9/99) - Professor X wakes the X-Men up at around five in the morning for a training session, saying that they have become lax in their combat skills and response time. He acts pretty much like a poopoo face the entire issue, most notably when he tells Kitty that Excalibur was a failed experiment and that she doesn't think. He tries to push Marrow to further learn how to control her bones by commanding her to make her horns disappear. She is able to do so for a few seconds, but at excruciating pain. When he tries to get her to do it again, Gambit stops him and then storms out.
