Whassup?!!?

Ethan has recently developed his own version of this um, word...? But his is, whassat? Translation: What's that? He says it all the time while pointing at various objects. I can't help but think of those crazy commercials...
He also loves to growl at various animals/animal pictures, and attempts to make all sorts of animal noises. Today he accidentally snorted, and he got really excited and made his sign for pig. That was pretty funny.
