Three nice groups - the Random advice one felt a bit tacked on though (and also stood out like a sore thumb).
While not everyone likes four groups that work in a similar way, I notice that "Ball" and "Bath" both can be preceded by "Foot"...

Mister Tom, what do you mean about foot and ball?a red herring?

Great grid. The bull group was very nice in retrospect, I guessed Ducks for it because of Sitting.

I liked it
