So numbles became umbles, umbles beame humbles, and humbles are now called offal.
And offal is often used to mean refuse and garbage. Nof offal pie for me, please.
It sounds awful. And it is sneaked into hotdogs, and people don't know it.

Have you encountered andouillette? If you are seeking to eat cheaply in France you may well encounter it, but avoid it at all costs. It is a tripe sausage with added morsals of intestine. It looks grim and smells appalling. I imagine humble pie must be similar. Andouillette is not to be confused with andouille, which is OK. I have never eaten haggis, but I have my suspicions!

Haggis is yummy!

Ænigma disagrees. She says, "Haggle is Yuri!"

"Where did you eat this haggis?", he asked warily.

We're all spoiled by the low price of food these days. When half of a ;man's work went into
raising his own food, he ate everything but the squeal of the pig. And called it good.

At the First Unitarian Church in Ithaca.

Ahh. Not in Scotland then. It may have been Sassenachised (which is same as sanitised in this context!) for sale to the non-Scottish market south of the border and across the pond.

I tried it even souther of the border: in São Paulo, Brazil, on a Burns' Night. They had haggis for the intrepid and roast chicken for the trepid. I had a bite of my date's haggis. Jackie, TEd, don't go there!!! That was enough for me. Even if it was doubly sanitized.

Speaking of south of the border, I like menudo (AKA, sopa de tripas), too.

...haggis would be a piece of cake.

<ecch> you can have your cake, and eat it too!

piece of cake

That'd be piece of pie, Dub'. In this case humble pie.

And it is sneaked into hotdogs...

You know what Bismarck said, Dr. Bill.
