The Adventures of Rock

I am Mr. B and I live in the  in the house with Lady D and that was my sock:  I took my camera and searched out the other two possible culprits and this is what I found:

Bo

This is Bo, an 8 year old Pug who was locked in the house at the time of the incident, Bo is innocent of leaving a gift on my sock.

Ginger

This is Ms. Ginger, she also was in the house with Bo, she too is cleared.
