Here's the rub

[4GS]

Where does 'here's the rub' come from, and where is it's correct usage?
TIA

[China Doll]

Is it not a line from Hamlet? I thought it mean something along the lines of 'here's the problem.'

[4GS]

China, you're a genius lass,

[China Doll]

'...To sleep: perchance to dream: aye, there's the rub;
For in that sleep of death what dreams may come,
When we have shuffled off this mortal coil,
Must give us pause...'

Found the bit of quote I was thinking of. I don't know if this is where it originates though.

[4GS]

Thanks again China, it's stars galore for you today.
I never read Hamlet, but I did enjoy reading Shakespere when I was at school.
Think I'll visit a bookshop

it comes (via Shakespeare) from bowling - an obstruction or unevenness in the ground.
