Pooping like the doggies do

This photo will be best interpreted in the dialog prior to this event.  Gavin running is from outside "Mommy, I got to go potty. Go outside?" Me- "you can go potty outside G." Gavin- "I can go potty outside! Okay! Yeah! I go potty outside!"...Next thing I know we are cleaning poop off the patio with the hose.  Then he comes to me and says "I dont poop outside, only doggies poop outside."  Only a little too late.  Sorry for the nakedness of my child, but it was too funny not to post.
