You should do the following:
Take one paper bag. Find a freshly laid dog turd and place it in the bag.

Place the bag on your neighbour's doorstep. Strike a match and set fire to the bag.

Ring the doorbell.

Run.

and her dor is next to mine in the same aisle. I was going to suffer the bad smell for ages.
