I once buried a pet by digging a hole with a spoon. I wasn't drunk though. I'm guessing I shouldn't be saying that like I'm proud but I am actually swelling up with pride. I was crying my eyes out as well, sobbing uncontrollably. I probably looked a right mess.
And yes, I would be tempted to dig up the box when I move house just to see if its still there. In fact, I get tempted to do it every now and again... and as I dont have a trowel i'd probably use a spoon again
