Things I can do with my body on command:
1) Inflate my neck like a frog (Great party trick)
2) Push my nose all the way into my face.
3) Do the "walk like an Egyptian" head bob without moving any other part of my body.
4) Do the wave with my eyebrows both ways.
5) turn my feet at the ankles 300 degrees outward so they nearly face backwards.
If I think of more, I'll ninjaedit.
