In the Season 8 finale Janitor tells J.D. that his name is Glenn Matthews; "My Finale" was the series finale, in which Janitor's real name would be revealed. When J.D. asks why Janitor is revealing his name only now, Janitor points out that J.D. has never before asked what his name is, and proves that J.D. has already forgotten it. However just a few seconds later, someone else walks by and calls Janitor by another name, "Tommy," to which he responds.
