The time I successfully faked my own death taught me a lot about myself and showed me just how much the people I have known in the past couple of years cared about me. I don't really talk to any of those people anymore, save for one of them, but at the time it was a very good lesson to learn.

And seeing as I am in a long distance relationship and both of the people commited to it do not enjoy talking on the phone all that much (or really, it is just me) I would say that each and every conversation I have with her is extraordinarily memorable and worthwhile.

Also the time I successfully convinced a guy that I was a trio of sisters who were sexually active with their father's best friend and, sometimes, each other was as memorable as it was hilarious. It makes for a good story. It is a good argument for just how convincing and strange I can be.

I'm sure there are more, but those stand for now.
