One Piece
The longest-running opening rotation in television — more than twenty distinct sequences over a quarter of a century, each announcing a new arc.
One Piece opens with a main title sequence of 111 seconds.
At 111 seconds, it opens well above the 58-second median for animation sequences in this catalogue.
It arrived on Fuji TV in 1999, when Iron Chef, Digimon Adventure and Great Teacher Onizuka were also on the network.

South Park
A banjo, a cut-paper Colorado town and four boys at a bus stop — re-recorded and re-animated repeatedly across nearly thirty years while staying recognisably the same twenty-nine seconds.

SpongeBob SquarePants
A sea shanty led by a painted pirate head, in call and response with children — one of the most universally known pieces of television music written this century.

Family Guy
A musical number performed by the family about how television used to have values — a sitcom opening from the 1970s, done straight and then undercut.

King of the Hill
Four men drinking beer in an alley, and a guitar riff. Thirty-one seconds that tell you the show has no interest in going anywhere.

Neon Genesis Evangelion
Ninety seconds cut faster than the eye resolves, with whole frames of text and diagram flashed for one frame each. Yoko Takahashi's theme is bright, major-key J-pop laid over imagery that is doing nothing of the kind, and the mismatch is the point rather than an accident.

Futurama
Like The Simpsons, an opening built to differ every week — a new caption under the logo and a different scrap of old cartoon on the screen the ship flies past — wrapped around Christopher Tyng's theme and a crash into a billboard.
