LOLOLOL !!! The target sounds too funny -
Why not tell him to clean it up HIMSELF ? Put a note on the lid along with a roll of paper towels and maybe a little poem...
Just a quick note to say....
Please don't ruin my day.
If you going and missing.....
there'll be no more kissing....
If you really love me...
drop to one Knee.
Clean up the floor....
and I'll say no more.
