Not exactly talent, but I got dumb tricks covered.
I can rotate my tongue 360, make the end do the clover thing, roll it AND use it as a straw.
I can do the 'invisible lip string' thing like this:
I can belly roll up and down.
I can also do the "cross my index and middle finger and ring and pinky finger on one hand without using the other hand to help" thing but I never knew it was anything special!
I can imitate the full barnyard of animal sounds. Cow, goat, sheep, chicken, pig, horse, donkey... oh, and a seagull too.
I can give the middle toe.
...I spent a lot of time alone as a kid.
