Big Mean Chief B

"Nanny Nanny Nanny Nanny Nanny", she can get that out at 5 Nanny's per second - try it and you'll get the idea!

B: "Look what I made!" "It's an Indian Chief thingy!"
N: "Wow, that's awesome, let's get a photo!"
B: "Woo Woo Woo Woo" (or however you describe the word in Indian war cry language!)N: "Hmmm, you look like you're gonna spew! Try again!"
N: "That's a little bit better, not quite a spew but a bit of a yawn. Now try to look REALLY MEAN!"

And that's as mean as she could get!

N: "OK, Nevermind the mean look, try the woo woo thing again!"
N: "Still looks like you're yawning!'
And that was enough - she dissolves in a fit of giggles! I like that look best!
