I took a geology course in college. The raw giddiness the professor hit on seeing a very bland gray rock still makes me laugh thinking about it. Dude was starstruck by a large grey lump. I’m sure it was a very excellent rock, but I can’t recall now what made it so amazing. Something about glaciers.

I think he would have gladly licked the rock if he thought no one was looking.

I 100% believe the above.
