Be careful there, my dude!
Does your neighbour frequently visit the park from where you got the duck?
When was the last time you saw him there?
Maybe you should observe how the duck is behaving when it thinks that you're not around.
I used the WPA pin exploit on Backtrack r5 ages ago to get into my neighbors router when I was home on leave, then updated their routers firmware and maxed out the transmit power. I wonder if they ever noticed a better signal in their house. It was the coolest script kiddie hacking I did since getting friends to install Sub7 over AIM back in the day.
As a homebrewer, I concur. We used to keep a corporate beer or two for the guest that didn't want the carefully crafted, unflitered, organic beer. Called them 'guest beers'.
