Can you do any odd physical deformations/flexes?

I can also crack my left elbow very loudly when I open it in a certain angle, because I dislocated it at a very young age.

I readjust my knees and elbows every morning and they snap, crackle, and pop. I also sound like an old man creaking and popping when I get up from laying down for a while. I think I inherited that from my dad

I can turn my right ankle 180 degrees backwards after I sprained it really bad back in like 2008

it freaks people the forget out and it's hilarious

flex my ears, both

[Alyx Vance]

My jaw comes unhinged on one side
My leg can hyperextend slightly without any pain
I'm "double jointed" (my fingers can bend back farther than normal)
I can twist my thumb around
I can turn my twist my foot most of the way around but not fully.

Thats about it

i can wiggle my ears and one of my thumbs in double-jointed

[Candy Apple]

I can infinitely crack my big toes.
Like normally people can only crack their toes/fingers once in a while, I can crack my big toe as much as i want lol

[AtlasBlue]

I can move my ears back and forth.
Trust me, I've been called Dumbo more times than you think.

Nothing big but I can pop a large artery over my collar bone.
It's super squishy, if I ever need to die of blood loss real quick I can just pop it out and boom easy access.

nope

[Flatflyer]

well i can suck my cheeks in to the point where they both touch and you can see the space between my skull and jaw.

also i can crack my fingers infinitely and have a habit of doing it with my thumb by pulling in the first joint then snapping it back

[Swat 3]

I can't really move my 3 middles toes like in many ways, like all at once or none. Does that count?

Pretty sure this is everyone.
I can crack my right ankle indefinately:
Fun Fact: This started in Elementary school and the doctor keeps saying it is because I am growing at a very large rate.
