Good grid! :)

This one beat me, but still 5*s.
Hadn’t heard the light bulb story before.

(Cockwomble made me laugh!)

Everything everyone else said! Hilarious and challenging. What I love about yours is how completely unrelated the clues always look at first glance. Those are great grids, because they're full of light bulb moments. Do you see what I did there? :)
