An Everyday Infinite Loop

Got caught in a voice-mail infinite loop today. Caught only in the sense that I was stuck as long as I didn't hang up. Since it was an infinite loop, I had time to copy it down verbatim.

"Please enter the mailbox number of the person you are calling. If you have a mailbox on the system, press pound. For assistance, press zero."

Beep! That was me, pressing zero.

"Please enter the mailbox number of the person you are calling. If you have a mailbox on the system, press pound. For assistance, press zero."

I pressed zero a few more times, to get the sentence down, and see whether it would keep looping. It did. I was calling for a comment on a story. To be thorough in my reporting, I'm going to try again tomorrow, but looks like that one's going to be "could not be reached for comment."
