Ball Pythons too outgoing? (Picture Hassle!)

[rabernet]

Do any of you own Ball Pythons that are just too outgoing?

I just got a new camera and wanted to take pictures of all my Balls, but the main problem I had was that they wouldn't stay still! I would put my fingers on their head to try to get them to ball up, but they are too used to me! I was yelling at them to live up to their name and ball up, but it just wasn't happening. I had to be super quick with the camera to even try to get them in the frame.

Any one else seem to have this frustrating problem?

Freeze a metal bowl - put your snake under that bowl for about a minute (out of the freezer of course). Remove bowl and take pictures quickly.
