Scene:
Church Baptismal Font surrounded by a full family all in their sunday best
all the faces expressing horror and frozen shock.
In the middle leaning over the font is the young curate, sleeve of surplice rolled up to his shoulder fishing for something in the water.
His face expressing profound embarrassment he speaks;

“Slippery little buggers aren’t they!”

I remember seeing this cartoon somewhere in my youth and it has never left me.
I wish I could find someone to draw it.
