It Was Meant to Count Us

A program built to measure the internet copied itself until the internet slowed down. So did our clicker.

What happened

A committee member built an electronic clicker to count attendees, and it began counting itself. By 9 p.m. the tally stood at 2.1 million. The committee announced a record, then an apology, then a record again. The real number was worked out by hand the following week, and the committee still has not accepted it.
