Unique Souvenir Suggestions, Please

[thekrenz]

I live in SC and have a friend who will be traveling to London and
Dublin in the spring.  He has agreed to bring a souvenir of my choice
back from the trip, but I would like something out-of-the-ordinary. 
Would any of my fellow listmates be willing to offer suggestions? 
Feel free to email me off list, if you like.  Oh, and of course and HP
related item is a possibility, as long as it is unavailable in my
area.  Thanks in advance for your help.
