a little help?

A good friend of ours is getting married on Thursday and we are drawing a serious blank on a wedding gift --don't worry, I'm POSITIVE he doesn't read our blog :)--! They are registered at BBB, but I wasn't excited about anything that wasn't already purchased for them. So, if you would be ever so kind as to share your favorite wedding gift, that you received, or that you love to give (and please keep it clean! :) ) it would really help us out!
