You should basically expect him to jump all over the place!
Seriously, they bounce back to quickly your head will spin. The girls go through a more "serious" procedure, and they tend to get back to their old selves in 3-4 hours, so the boys - you can imagine.

Good luck, Chase!! /forums/images/%%GRAEMLIN_URL%%/smile.gif
