My grandfather wouldn't let my mother have a BB gun -- said it was too dangerous. Waited, got her a 22 caliber rifle. Less dangerous, because she wouldn't shoot someone as a joke.
This reminds me of what my friends and I played in High School. BB Wars! We played poor man's paintball. Facemasks, gloves, heavy jackets, pants, and single-pump bb guns. Talk about adreneline. It definetly was not the smartest thing we have ever done, but man it was exciting.
