Owed a Back Rub

Just last week, I banned boots from entering our house after seeing clumps of mud on the floor. The Hubby denied adamantly even bringing them in that morning until he saw the pictures.

After he came home one night, I found this, shouted "What the F! I'm getting my camera," and snapped a picture before he destroyed the evidence.

I also found out during Family Day that he often steps in cow dung out in the field. I think I should be compensated in some way. What do you think?
