I have a shed on the side of the house with a roller door at each end. This is handy to carry stuff straight through to the back or to park the car in (when I am out of lumber). Last night, since I had been in and out of the shed all day, I'd only closed the yard side of the shed and was just leaving the front door when I heard a noise in the shed.
I snuck around and peeked into the end of the shed and, in the gloom, saw the tail of Sally the shop dog happily wagging as she was tearing into a bag of MacDonalds she'd dragged from the bin.
Since she knows this is a definite no-no, I thought I'd teach her a lesson and scare the bejeezus outta her. I snuck up on her as quietly as I could and, I must admit, did a great job of it. Trying to stop myself from laughing, I slowly reached to grab her in the ribs and yell out. Thankfully, the wind was blowing toward me and she didn't catch my scent.
Anyway, she was buried deep in the McBag (it was over her head) and her shoulders were half under the shelf. Perfect, the silly mutt was gonna freak out.
I grabbed her ribs and yelled "Bad Dog!", then started laughing - for about two seconds...
What came out of the bag was not my dog! It was someone else's Labrador wearing a surprised look and lots of teeth. It had banged its head on the way out from under the shelf, then had backed between my legs, snapping and snarling - not good. Inside the house, my dog was now going nuts, further scaring the new dog. I went ass up trying to get away from the teeth and paws of the mutt desperately trying to get away, which thankfully it did. Leaving me, totally shattered, in a heap in the shed.
It took hours for the heart rate to go down.
