My wife & I once attended a semi-formal dress Scottish event at the local civic center. I forget the exact focus, but the event was replete with bagpipes, kilts, and a processional for "bringing in the haggis".
Also seated at our table was an older, scholarly-looking gentleman who was apparently married to one of the event's (Scottish) organizers. He declined the haggis when the server got to him. After everyone was served, and I was getting ready to try haggis for the first time, I asked him why he declined. With a knowing smile he said, "I know what's in it".
Not something I could eat every day, but thought the haggis was good.
