This year's best story definitely goes to grandmother showing everyone the burn marks from the shell casing that fell in the front of her blouse at the gun range, and the ensuing discussion between her, her niece (my mom's cousin, my aunt/second cousin once removed) and my sister about the ethics of using a firearm for self defense. (Grandmother wouldn't hesitate to shoot a person causing harm to her family, this, along with her recent RV camper purchase, concerns me somewhat in light of her appreciation of the t.v. show Breaking Bad).
Last year also had a good near-incident, involving a second cousin of mine, a unicycle, and I think it was a stand alone fire pit.
There's also been a lot of talk about the deep fried turkey that may or may not have been there.
I'm not entirely sure what that might tell you about what my thanksgivings are like.
