Arbitron will never figure it out, too.

Arbitron uses a percentage of RDD calls (Random Digit Dialing) to know
prefixes. This is to pick up unlisted phones in proportion with their
presence in each metro. Some will be inactive. Some will not answer. Some
will be faxes. So they perform enough calls to get the proper quota of
unlisted numbers to get market proportionality.

It doesn't matter that the comedian expected to get the pie in his face,
it's still funny to watch it happen.
