Lol, buenchico i have to say that this bit from your link made me laugh.
"I have to say that I don't accept this answer. I've cooked toad-in-the-hole many times and it doesn't look like a toad sticking it's head out of a hole. In fact, if I wanted to name the dish based on what it looked like, I'd call it snake-in-the-sand or worm-in-the-dirt. Granted, they're not as catchy as toad-in-the-hole, but it looks more like the dish itself."
