Crazy Tongue

I can flip my tongue upside down like she does at 0:10. I've been trying to figure out how many other people can do that. :confused: I can't do the wavey stuff. I wonder if one can learn to do that.
 
I can roll my tongue into a tube, and flip it upside down both to the left and to the right.

But that girl's got one amazing tongue and one very lucky boyfriend!
