The Simpsons sitcom has been running for so long that it has gone from incorporating pop culture icons into their episodes to becoming a pop culture icon itself. The cartoon is instantaneously recognisable by legions of fans and non-fans (what’s wrong with you guys?) alike.

It has throughout its 25 golden years blown through so many celebrities (approximately 500) that it’s easy to forget who has been on the show and for which episode. We’re feeling a tad nostalgic at the thought of the 26th season hitting television screens soon with its 2015 celebrity line-up in tow (Pharrell Williams – and his hat, Elon Musk and the cast of Futurama) so we decided to get down to rounding up some of our favourite celebrity cameos on The Simpsons.

10. Russell Brand

Episode: Angry Dad: The Movie

Favourite Quote:
Jamie Hyneman: Tonight we take on the classic myth that a cat will always land on its feet.
Adam Savage: We didn’t want to hurt a real cat so we took this Build-a-Bear carcass…
Jamie Hyneman: Stuffed it with ballistic gel, shot it with a 20-foot barrel steam cannon…
Adam Savage: And made a scatter plot of the remains. Booyeah!
Jamie Hyneman: What was it we were trying to prove again?
Jamie Hyneman: Don’t know, don’t care.
7. Benedict Cumberbatch

Not many people know this but it was voice chameleon Benedict Cumberbatch that voiced Alan Rickman’s role as Professor Severus Snape.

Favourite Quote:
Dr. Hibbet: [MENSA Club is giving a public speech] When are we going to get to my speech?
Comic Book Guy: Quit butting in please. Your IQ is a mere 155 while mine is a muscular 170.
[singing to the Star Trek theme]
Comic Book Guy: I am smart. Much smarter than you, Hibbet!
Professor Frink: You should do what I do. My IQ is 199 for crying out glaving.

4. Agent Mulder & Scully

3. Leonard Nimoy

Episode: Marge VS. The Monorail
Favourite Quote: “A solar eclipse. The cosmic ballet goes on.”
2. Johnny Cash

Episode: El Viaje Misterioso de Nuestro Homer
Favourite Quote:
Coyote: I speak of a deeper wisdom. The problem, Homer, is that the mind is always chattering away with a thousand thoughts at once.
Homer: Yeah, that’s me all right.
[gets a glazed look in his eyes as the wind blows his hair]
Coyote: Clarity is the path to inner peace.
Homer: Well, what should i do? Should I meditate? Should I get rid of my posessions?
Coyote: [snorts] Are you kidding? If anything, you should get more posessions. You don’t even have a computer.
1. Michael Jackson as Leon Kompowski

Michael Jackson wasn’t technically credited with the voice of mental patience Leon Kompowski (due to contractual restraits we’re told) but there’s no mistaking the uncanny resemblence. The quote isn’t funny per se but we wanted to highlight the variety that is The Simpsons. It’s not always comedy gold as they’ve got a firm hand on the soaps too. Oh, the feels.
Episode: Stark Raving Dad
Favourite Quote:
Leon Kompowsky: You know Bart, when I was growing up I didn’t have much money. So you know what I did every time my sisters’ birthdays rolled around?
Bart: Stiffed them?
Leon Kompowsky: No Bart, I wrote them a song to show them I cared.
Bart: I can’t write a song! I’m only ten.
Leon Kompowsky: ONLY ten? When I was your age, I had six Gold records.
Bart: Hey, Looney Tunes!
[pulls out the Thriller album]
Bart: THIS is what Micael Jackson looks like! You just look like a big, fat mental patient!
Leon Kompowsky: You’d be amazed how often I hear that. Bart.
