d4 give you two bits at a time, d8 give you three, or d16 give

readily available.

 True, that will work.  Die for generating, pencil and paper for
'recording' the result.
 However, if one had pencil, paper, and no die anywhere?

Write down a number on a little piece of paper front and back and crumple them a bit. Then expose them a fan where they start blowing all over for a while. Turn the fan off, then look at where they settle? ;^)
Almost akin to confetti that has numbers on it? lol. :^)

 

As well, with just pencil and paper, obtaining a Unix epoch is quite
an interesting 'by hand' calculation in order to perform this:

You can skip that part by pretending it's 1970.

 Very true.  Although then the offset random number is also identical to
the non-offset number.  Not that the offset is actually doing anything.
