I got my 10 yr old nephew to alternate panels with me on this 16 panel page I threw together quickly on a 11x17 card stock. I started off and went from there. I found he is a pretty funny, little guy and has a decent grasp of the medium. Some of his panels really made me chuckle. I got the idea from Scott E's strip jam project up in the Community section at Penciljack.com.
The orange panels are mine and the blue ones his.
