I thought they were called “credit cookies.” Or is that something else?
I always called 'em “Wait til the end of the credits, lets see if there’s anything.” But, I do like credit cookies 
I knew that from Mystery Science Theater, which made a tradition of it. But at this point, I think of post-credit scenes as “obligatory 5-second wastes of my time that weren’t important enough to be in the movie in the first place, and are not worth my sitting through 12 minutes of credits when I could already be out the door and halfway to dinner.”
Stinger’s shorter, though.
I don’t know if I’ve ever heard the term, but that what I assumed they were called.
Didn’t know that. Thanks - ignorance fought.
Sometimes “Monk’s reward.”
That’s what Roger Ebert calls them. I don’t know if he coined the term or not.
By the by, do we have a thread to list them? I have a collection in my personal memoirs that I’d love to share (and to augment)…TRM
I disagree. I, for one, feel it was vitally important to learn that Skeletor was still alive at the end of Masters of the Universe.
Oh, I don’t know, the bloopers at the end of A Bug’s Life and Monsters Inc were very worth the wait. However, I did hang around through the credits of Finding Nemo hoping there would be bloopers…and there weren’t. 
I also learned they were called “stingers” from MST3K
also, if you’re watching a movie in theaters, keep an eye out for a small oval dot to appear in the upper right corner of the screen (black dot with a white border) for a fraction of a second, count to five, and you’ll see the dot again, those are called “Cigarette Burns” (Cue Marks) and they’re there to tell the projectionist that he has five seconds before that reel of film runs out, the first cigarette burn is on the old reel, the second one is on the new reel
I learned that from “Fight Club”, only problem is now whenever I go to the movies, I see the Cigarette Burns every time and start mentally counting off that 5 second delay and looking for any visible sign of a projector changeover, they’re no longer invisible to me
IMDB.com lists them for each movie under the heading “Crazy Credits.” Look down the options on the left-hand side of the page.
I’ve heard “stinger” used on CBC Radio to refer to a short piece of music played after an interview as a bridge to the next interview.
Why does Ebert call them Monk’s Reward?
Because it takes the patience of a Monk to sit through all the boring, useless credits until you get to them.
By the way, I *always *sit through the credits, even if there is no “reward,” because I like to see filming locations, what kinds of watches were worn, who supplied the silverware, and all that kind of trivia. Yes, I’m a geek…TRM
I like to sit through the credits just to look for odd and interesting names. How else would I know that there were people in the world with names like Geefwee Boedoe, Greg Killmaster, and Elfie Shlegel (unfortunately I don’t recall how to actually spell that last name so I can’t look the person up on IMDB).
Count me in as one who stays through credits and has for years, so I appreciate pirate monkeys.
Ever since I found out what I missed by walking out of Young Sherlock Holmes before the end of the credits, I’ve always stayed.
One memorable stinger for me is at the end of the independent British vampire film “Razor Blade Smile”, the lead character, Lilith Silver, an assassin who happens to be a vampire, has been eliminating people who are on her trail, it looks like one of her witnesses has escaped with her life, after the credits roll, we see her preparing to take a bath, the camera is at a low angle behind the faucet and spigot, she turns her back to the tub, starts to disrobe, Lilith rises from the tub, grabs the woman in a headlock, and prepares to bite the survivor’s neck, the camera freezes, and we hear Lilith’s voice say…
“I don’t know about you, but I hate leaving loose ends”
…and the film fades to black
I presume that you mean zombie pirate monkeys.
