I really like that you are clever enough to use a couple of wrenches as your "busy tools". I was working with a guy that grabbed a 12 lb sledge to carry across the lease to look busy. I grabbed half a coil of twine and a pair of nippers. He was tired out from looking busy at 2 PM and I lasted until 7 PM for two hours of OT. That guy didn't last.
Also, I found that the peckers really like the tin flashing above my bedroom in the morning, so I rubberized it and after the first three got whiplash, I think the word got around to fly right by.
