The photo in the main article (the original HN post) appears to be from 2015, though, because Woz seems to be wearing an Apple Watch.

One time I found a wallet on the beach and took to the local cop station.

They started questioning me in a way that seemed to suspect me of something. When they asked for a name and address I gave a fake name and 'no fixed abode'.

F#ck them I say, the suspicious bastards

For what’s it’s worth, depending on jurisdiction you either have to respond to these questions or not, but it’s always wrong to lie.
appease7727•6mo ago
No, lying to cops is always correct.
d1sxeyes•6mo ago
Yeah! ACAB! etc. I meant wrong in terms of lawful/legal.

I'm not sure about state/local police but it's definitely illegal if it's a federal officer: https://www.justice.gov/archives/jm/criminal-resource-manual...

I actually looked at getting a sheet of these when I was at Treasury after touring the printing but they charge a pretty steep markup for their bill sheets. It goes as high as just shy of 200% for the smaller 4 note sheets (sold for $22) and gets better until you reach their full sheets which are 32 notes (still sold for $102). Ended up not getting one because of that.

They'll happily ship them to your door if you're interested: https://www.usmint.gov/paper-currency/uncut-currency/?start=...

Most banks will have a brick of $2 bills - often new, with consecutive serial numbers. When I traveled for work, I loved tipping with these fresh bills. Some folks would wonder if it was real. Some would think I just handed them a collectable silver certificate. Most important, both Bride and child were too embarrassed to spend them - so they could just be left on my desk.
