As we have a thread about popular things we hate, I thought it might be fun to hear about the opposite.
Unpopular things that I think are great include:
Bagpipes
The deeply unfashionable Fairport Convention
Pickled gherkins/ onions/ beetroot/ cabbage!
I draw the line at pickled eggs. I was given one in error at the chippy once, and namely tried it. It was like trying to bite into a bouncy ball.
