Here's a problem that *sounded* impossible... I almost regret posting the
story to a wide audience, because it makes a great tale over drinks at a
conference. :-) The story is slightly altered in order to protect the
guilty, elide over irrelevant and boring details, and generally make the
whole thing more entertaining.

I was working in a job running the campus email system some years ago when
I got a call from the chairman of the statistics department.

"We're having a problem sending email out of the department."

"What's the problem?" I asked.

"We can't send mail more than 500 miles," the chairman explained.

I choked on my latte. "Come again?"

"We can't send mail farther than 500 miles from here," he repeated. "A
little bit more, actually. Call it 520 miles. But no farther."
