Prawn sandwiches

Mention of this on the rugby thread has got me thinking.  I love a prawn cocktail but will never understand the desire to put prawns in a sandwich.

Do you have the same aversion towards crayfish in sandwich?

I dislike prawn nigiri when it comes to sushi--it's flavourless, its chewy/slightly rubbery texture doesn't go well with the rice, and there's that awkward bit with the inedible tail.
