Tommy & Georgia are watching and
istening to a new rock band (SME) rehearsing.
Georgia:(talking about SME to Tommy) Do you think you can
get them ready in time?
Tommy: Well... I mean they're seriously rough around the edges...
I mean in fact they're all edges, (Have a lot to refine?) but I think I can make it work.
Yes. They are very rough indeed. ("They're all edges" is not a standard idiom; it only makes sense as a play on the earlier "rough around the edges".)
Thanks, Mr Wordy!
