Neighbor kids were shooting each other with a bb gun
What started for them as fun started to get ugly and mean fast. One brother dropped his pants and mooned his brother who was aiming at him. The mooner got hit in his 'appendage' that was exposed below his moon.
When his mom got off work she found him crying sitting in a filled up bathtub with a rather sore and inflamed "area. She took him to the ER (this was pre-urgent care days). She then sold their bb gun.
