Update: it turns out that the phone number in the Spider Monkey ad is just the phone number that you call to get the time and temperature.

That raises the question of who bought the ad in the first place. Here are some possibilities:

1. It was a joke to rile up animal lovers like me. (Most plausible.)
2. It was a misprint.
3. It was a coded signal. (Most intriguing. Unfortunately, I don't know who it would be targeted to, and I don't have any clues about what the code might be. Maybe if I were a cryptographer or a puzzler I'd have better luck.)
