I'm too faxy for this job

Several years ago I worked in customer service at an electronics store. There was a salesman there, I forget his name, but he was as close to Dwight Schrute as you are likely to find in real life.
One day he faxed in sick.
The next day he faxed in sick again.
The third time, the manager asked me to call him and request a doctor’s note.
He replied with a letter of resignation. By fax.
He asked that his last check be sent right away.
I faxed it to him.

I remembered that incident when I was reading this genius reply to a debt collector. Hilarious!
