The other day Jacki asked me if I could do a cartwheel. Pshhh. Of course I can. Well, I proceeded to demonstrate my "cartwheel" and it was appalling. Ever since I've been practicing my cartwheel (sometimes in my muumuu). Pace has also been trying to practice his, but to little avail.
Here is the classic headlock position. Pace gets these frequently... while he gets sat on.
