I was at a bar with a friend years ago and he kept talking about how much he loves limes. He went on and on about it. Finally, I told him I would bet him $50 if he could eat a whole lime, rind and all. He couldn't refuse after spending 10 minutes talking about his love for them. The bartender was happy to offer a large one for the challenge.

This kid tried for 45 minutes to consume the lime. The juicy interior was quickly consumed and all that was left was the bitter, leathery peel which had the surface area of a dessert plate. He was chewing on it like he was trying to get someone to guess "chewing" in charades. He, very begrudgingly admitted defeat while me and the bartender were breathlessly laughing.

I'm a sideshow performer. One of my sillier "tricks" is eating fruit rinds.

Impossible: coconut, mandarins/clementines (you can bite them but it's like chewing leather)

Tough: Watermelon and pineapple. Bananas are also hard because of how dry they leave the mouth. These are the ones I do most often. I like to bring someone up on stage to join me

Easy: Lemon, lime, most oranges

Better with the rind: kiwi, ripe mango

Wham bar

Steak from New Zealand.

Rice cracker mix from Golden Turtle (Yoshino Mix).
As hard as a solid rice rock.
Nothing for weak teeth.

mouth guard, one of those off-the-shelf ones that you boil. got most of the way through it before i managed to get a real one from my dentist.

Sękacz (Polish hard cake, some people make them as hard as a dwarf bread from discworld)

A steak our vegetarian neighbor fried for us. It was embodiment of "haven't cooked meat for 30 years"

She makes great non-meat foods though!

I once bought these chocolates that had a outer coating making them look like decorative rocks.

My mum loves to have little rocks as decoration so I bought a pack and decided to surprise her with it. Out of nowhere in front of her I decided to bite through one and she was in shock looking at me as she slowly realised they were edible. They looked extremely convincing.

They were pretty damn hard tho. Nothing too bad however.

At one point it was breaking my Mint install having to learn how to fstab and do all sorts of commands to get my data back. Took me something like 11 days and it wasn't just UUID errors I somehow borked it so bad there was multiple files wrong. I've now learned a ton. I've done it atleast 6 times more and can fly through fuck ups in minutes. I nearly gave up. Encryption isn't always the easiest to play with either.

Edit. After reading the other comments you were serious about eating/chewing no hard problems one had solved. AKA accomplished.

Probably the inside of a tootsie pop that was so hard and chewy it nearly dislodged my tooth. Pulled out a filling. I bit down on it and couldn't get my teeth separated in the back it was like glue. Fucking good though. I eventually won.

Plastic wrappers/pouches when the tear points don't work.

Fuck plastic packaging they need to be banned. Not just for this reason obviously.

Probably umbilical cord.

Probably a large ice cube, or a piece of candy meant to be sucked not chewed.

A piece of gristle the first time eating at my girlfriend’s parents' house.

The head off of a salmon

Fla-Vor-Ice tubes.
