He's a stand up guy.

As of yesterday, Jasper stood. By himself.
That is if you stand him up and then let go, he can hold it for a moment.
But still. That's an awesome skill for someone that's been on this planet for less then 9 months.

5/18/11 - UPDATE: Tonight Jasper was standing at the coffee table and let go, stood there for a second, and then went back to holding on to the table!
