Last time you had to 'clear' your house

[muddywings]

So my most awesome dog (see other recent thread) never barks unless a squirrel has invaded the back yard. Even then she only barks once or twice as she chases it away. And, since I trained her not to bark as a puppy (I don't like dogs that bark), she always comes to me with her head low in shame. I don't mind so I always tell her "good girl" and pet her when she chases that pesky squirrel out. Not a big deal. But she knows better than to just randomly bark.
My dog is NOT a guard dog, at best she is an alert dog. If a bugler came in she would probably point him to the fridge and ask for some left over chicken but ferocious she is not. I don't need or want a a guard dog. I have a Mossberg for that.
Anyway, my dog has never barked at night. But last night, 2 AM, I hear "WOOF WOOF WOOF GRRRR."
Oh crap!
We do have a dog door and I don't lock it at night. I figure if I have to get up once or twice a night to relieve myself, she has the right to as well. I know this is the week point in home security but I live with it.
Anyways, I grab mossberg and clear the house. I'll admit, 2 AM is a tough time to clear the cobwebs and put my A game on. In the end, it was nothing but did make me realize i should practice clearing my own house a bit more often. A few amateur clearing mistakes.

When is the last time you had to clear your own house?
