The context I have heard the ham and eggs analogy was for certain scrum rituals that were supposed to be for ham people only (ie, excluding people without a stake in the outcome). Someone probably told this boss to butt out of a meeting.
It is all dumb stuff, imo. 00's agile got away with a lot of stupid things - usually with the implicit aim of increasing the number of billable devs (or to sell conference tickets or books. It was almost like, the more absurd, the better. There are still remnants of that but, thankfully, it has mostly disappeared.
