People that should appear on the Simpsons before it's too late!

I don't care if the newer episodes of The Simpsons are considered to be awful or not the same as it used to, I've decided to create this list being based on the celebrities I'd like to see them and should appear on the Simpsons before it gets canceled for real. If you truly want to know the main reason it's because I am really starting to get ticked off of how many great and interesting celebrities are appearing on the other shows I don't like especially the ones created by Seth McFarlane (the idiotic FG and stupid AD both God-awful shows that are barely watchable these days) I really don't get the idea why so many great celebrities appears on some of the worst shows out there? I want to see these celebrities to appear on a more smarter show like the Simpsons besides it's better and funnier to see them get Simpsonfied. To be honest the Simpsons needs more potential celebrities than what those other shows gets. This list is NOT complete and probably won't until the show is cancelled! Plus not in particular order either, it is completely random.

If by some blind luck if some of the writers of The Simpsons would see this list let me estimate that I don't want this to look obligatory, but at least try to ask some of these great celebrities if they have any interest to appear on your show so don't be afraid to ask them gently. Please not for the "vanity" but for at least some pleasant presentation. You guys deserve more interesting celebrities and there are plenty of them to ask so just do it!

It would be alright to see any of these people either to play themselves or as another kind of character as long as we get to hear their voices. And also appearing at least for one section of an episode is fine to me, two can be alright but not on the entire episode so it won't look like a commercial for the certain celebrity like it happened to Lady Gaga and Elon Musk, if you at least can come up with something witty at least.

Let me also estimate that I don't want this list to be considered one of those idiotic, pathetic and pointless "people that are considered to be hot but are not" lists, No this is NOT one of them I'm being totally serious here guys! I love most of these people no matter what and I don't want to make fun of anyone here. Every people here on this list are 100% welcome to appear on an episode and as long as I find out that at least some of these have appeared I will make another list by putting them there instead (which coming soon hopefully) depending which one has.

If you happen to a a fan of the Simpsons and are fans of these people here PLEASE help these great people to appear on a Simpsons episode with themselves!! At least try to convince them via Facebook and Twitter or any where else!!! Don't you just sit there and watch this list! Do it now!!

UPDATE 2015-05-08: An all new list has arrived where it involves people from this list that finally arrives on the Simpsons! Here's the link: http://www.imdb.com/list/ls072538023/

F.A.Q.

Why haven't you put celebrities like Anthony Hopkins, Quentin Tarantino, Bob Dylan, Bruce Springsteen, Michael Caine, Clint Eastwood, Tom Cruise, Don Rickles, Pearl Jam etc.? It's because these following people have unfortunately declined to appear. Although I wouldn't mind if they would finally appear in one if they have changed their minds.

Can I request for a celebrity? Sure thing just comment for what celebrity you'd like to see appearing on this list if you haven't found your favorite idol/idols over here yet.

What happened to some of the people you added and then they're gone? It can depend, I might have recently found out that a certain celebrity on this list have appeared on an episode. Or I might have found out that a few of them have already rejected to appear in one. Or if a certain celebrity passes away then he/she will also be removed from this list, of course not because I changed my mind but because it wouldn't make much sense if a passed away celebrity would appear on an episode.
