Troubles With Anecdotes

Everyone loves a good story but what everyone loves more is an anecdote, good or bad. Not only do I love hearing anecdotes (especially from relatives), but I love telling them too. They add sometime special to a conversation (i.e. comedic relief). My problem is that I forget my best ones when I have the perfect situation in which to tell them. When I finally remember the short story I'm usually in a different location with a different group of people, so telling my story is pointless. Sometimes I'll tell it anyway just to get it out of my system. I would provide an example, but naturally I can't think of one. It's interesting that I'm so fond of something I have trouble properly executing. And still I try.
