404 - Mark not found

The Mark you seek could not be found.
Is he above or below ground?
I am not sure, I do not know.
I never see him come or go.

---

Here are some suggestions:

• Make sure you spelled his last name correctly.
• Check under his desk.
• If all else fails, this advice is often useful not only for locating professors, but also for locating Marks, and indeed, just about anyone or anything. Or so he claims.

Perhaps the reason that you came,
Is that you seek some printout with my name.
