LOL, I love GIR.
"No GIR, that's bad." -Zim.
"YAY!" -GIR
We love GIR too.
Caitlin can do a spot-on GIR imitation.
Mimics the voice, and since she's got a great memory for lines, she says stuff.
Usually she'll wait til I'm scolding her, then she gets this daffy look on her face, slaps on her GIR persona, and then says something like :
"I got chocolate-bublle gum!"
or
"Me and the squirrel are frrriends!!!".
And then I laugh, and while I still make her do what she's supposed to do, it's less Old Testament than it might have been.
