some of these I had noticed before, like the L-shaped sheets, but others I totally overlooked, like number 28...

Some funny stuff! And quite a bit of it is true, when you think about it.

lol, good stuff!

on number 28, Archie's dad tells me that with early phones, that was how you got the operators attention, so I guess movies still use the image even though it doesn't work on phones today

Well, #14 and #5 are true, to an extent, anyway. You just have to have some skill picking a lock.
