Closest....about 12 inches to a mouse...not a rifle but a shot gun and a funny story....
We live in the country, our house is in the middle of what was once a cow pasture. We get mice in the house, no way around it. Well I had a glue trap out and a mouse got stuck.....If you have ever had this happen you know the little suckers just scream and scream till they wear out and die....well this was the wee hours of the morning and the wife and I are in bed trying to sleep...and she hears the squeaking....she tells me to do something...me being the devoted husband that I am try to pretend to be asleep....she keeps at it....finally I tell her it will be quiet in a few minutes after it dies....she tells me that is terrible and to do something about it...that requires me getting up I say, and that it will be dead soon....but not soon enough. Mouse is still squeaking, and the wife is getting insistent....ok I say I will get up and smack it on the head with a hammer.....oh that is so mean....you can't do that....ok whatever....so I get up, grab shotgun, grab mouse stuck to trap...go outside, put mouse on ground and blammo....no more mouse....not sure where he went, but he is gone, and I go back to bed.
