Sitting on a time bomb?

Talk about living with danger…

Construction workers replacing siding and insulation in an old house in Charles Town, W.Va., made an explosive discovery.

Well, not literally, thank goodness.

But they did find a 10-pound live artillery shell sitting on a sill plate.
The new owner of the old house, American Public University, gave the round to the Jefferson County Museum.

A board member there said the shell probably lodged in the house during a fight on Oct. 18, 1863, when Confed-erate artillery fired on the courthouse.
And there it sat for nearly 150 years, safe as — well, like the old saying goes: 
Safe as a house.
