A hole in a brick is called a frog sometimes. This is because often on job sites or ones who sat out for lengthy times on their sides frogs would decide to move into.
Well if a frog is on a brick even though it is in truth attached to a piece of rock, the frog doesn't change form, and is indeed, still a frog. creative question by the way.
I have just measured the diameter of a perforation of a three hole perforated brick(UK 1960's) it was 35mm diameter the brick itself was W102.5(approx') x L220x H75; I haven't got a v frog brick to measure single or double.

The reason for the recess in the surface of frogged bricks being called a frog is not known.A:One theory is that as the block used to press this indentation is also called a frog, possibly based on the appearance of this block especially if some clay adheres to it, and the name was transferred to the recess created in the brick by the frog.A:Another theory is that the similarity between the recess in a brick to the recess under a horse's hoof is the origin of the name "Frog".The compacted mud that drops out of a horse's hoof can look like a crouching frog or toad.
