I can grab my toes together like one would with their hands, you know fit one hand into the other but then with your toes.
I can also do the preggo stomach and I have hyperflexible joints in my fingers.
Also I have slightly better toe control than most and I have shoe size 15. I can grab stuff with my foot and throw em up and catch em with my hand and stuff
I've been doing the extended stomach thing since 3rd grade LOL I can push it out REALLY far to where it looks like im about to give birth. Freaky. When i had a 6 pack and would do it, people's jaws woudl drop! I'd day"see these abs?" (lifting my shirt up) then poof pop it out real fast and they're like WHOA.
Also double jointed so i can bend my fingers at the first knuckle while keeping the rest of the finger straight.
As a kid I could flip my eyelid inside out. Havent tried that in some time cuz frankly it would probably really hurt.
