But have any of them quite topped the boggle-eyed, boob-waving antics of this year's I'm a Celeb enfant terrible Helen Flanagan?
Ant & Dec are usually quite difficult chaps to ruffle. Hosting a series of I'm a Celeb for the Geordie duo is conducted with the same ease that most of us complete a supermarket shop. They fly to Australia, play some golf and occasionally take a break to make some funnies about washed-up '80s celebs.
But even the unflappable Ant & Dec have shown signs of frustration at the ongoing joke that is Flanagan's bushtucker blubbering.
Flanagan promised us "depth" and a "complex" character. So far she's shown us her boobs and not a lot else.
When not balancing her 'Flanagans' inside her itsy bitsy bikinis, she's usually in one of two states: Tears or hysterics. The briefest sight of a maggot, the slightest glimmer of a cockroach, a sniff of a rat and the Corrie actress-turned-Twitter cleavage flasher can barely control herself and is quickly issuing threats that she'll be out of the jungle in a jiffy if a critter so much as looks at her funny.
While we certainly don't want Flanagan to walk, we won't rest until she's been made to suffer a truly atrocious bushtucker trial to its proper conclusion. Someone stick her in a box with some snakes quick.
During Thursday night's Cruelty Towers bushtucker, Flanagan was tasked with collecting stars from various rooms filled with jungle animals. She failed to get past room one after coming across an ostrich, who she named Olly. By the end of her melodramatic attempts to retrieve the first star, we felt more sympathy for the distressed Olly than the red-in-the-face soap actress.
But maybe you think we're being harsh on Helen? Perhaps whimpering Hugo is getting your goat? Maybe Nadine Dorries's attempts to change the face of British politics by eating some camel toe are grating you?
Or maybe you stand by the rule that there is nothing in I'm a Celeb history that can ever be worse than Kilroy-Silk?
Whatever your opinion on Flanagan, she's certainly making a name for herself in the jungle, which was probably her intention all along. So maybe the biggest joke of all is on us.
