One of the podcasts on Smash Notes is called "My Dad Wrote A Porno" and apparently it is extremely popular. The author was in his 60s when he heard about the success of 50 Shades of Gray, so he decided to write his own.

The script is so awful, it is hilarious. Author's son found out about the porno and turned it into a podcast, which gained a following and is now an HBO show.
