Ha, you just made me look it up in my inbox. Here's the ad copy:

Hello Listeners!

This is not an ad. Grumpy Old Geeks are selling ads at a discount, so I bought this slot. I have no product or service to sell.

I hate ads. Don't you hate ads? I just saved you from having to hear or skip an ad! You're welcome!

If you aren't running an ad-blocker in your browser… what's wrong with you?! If you aren't subscribed to GoG to avoid ads via the private feed… that's your call. But I'll never hear this because my stream is ad-free. I never thought I'd pay for marketing, but this seemed like a fun idea. Also, check out the fediverse.

Deliveroo, Fuckers!

Love,
Your pal, another listener.

It ran for $125. It appeared in the episode after 2023-06-27, based on my email correspondence with one of the hosts. So whichever one was next after that.
