Sat in your lap

[Tavares@MIT-MULTICS.ARPA]

I'm not convinced that you didn't get the idiom backward.  "Knowledge is
something sat in your lap" implies that you can have it given to you, or
magically acquire it, or the like (i.e., a windfall), but you can't get
it by working at it no matter how hard you try.  For example, winning
the lottery is sat in your lap.  Sum God's chillun gots it, others nebba
will.
