It messed with my head for a minute. I opened that bag and dumped everything out not looking at any of it, then I took my actual stuff out of the box and looked at it, put it all away, came back, and there was this shaver and the packing material on the workbench.
I was thinking maybe I had left it there earlier but didn't remember, and had a real "WTF" moment, I thought I'd lost my marbles.
