Moodles' Cthulhu Face is rapidly becoming a sekret handshake of sorts around our house. Moodles is tickled with it, because it's something she can do that she knows Momma and Daddy will do back. These last two days, she has gone out of her way to look at me and then give me the Cthulhu-finger-waggle. She then looks inordinately pleased with herself when I respond in kind.
This is made more amusing to me because, for all our many repeated attempts to show her how, we still can't get her to wave goodbye or hi-five reliably... But she will now make the Cthulhu face very nearly on command.
The most recent variant on this theme is the "Kiss of Cthulhu," which has become highly popular at diaper changing time. When she tries to roll over on the changing table before her diaper is firmly affixed, I have only to palm her face and make kissing noises on the back of my hand while tickling her cheeks and ears with my finger tips, and she dissolves into gales of giggles. The giggling usually gives me enough time to get her dressed again without struggling or tears - if I'm quick!
In my 20's, I used to tell people that I wasn't going to have kids until I could get my pets right. To this day, most people will tell you that my dogs just ain't right... They are affectionate, and they mean well, but they ain't right.
... At least my results continue to be consistent...
