Which film had the best after credit scenes?

So by now just about all of us are staying for the end of the films to see what extra scene will be at the end of the credits. Sometimes they're awesome, sometimes they're funny, and sometimes they're really stupid and kind of a waste of time:whatever: but they're usually worth the wait. Which is your favorite scene? Marvel has spoiled us rotten and now do a mid credits scene and a end credits scene in their films so I will be including both in the poll.
