Something on radio 5 other day about mistakes people make with "well known" phrases or expressions.... Such as damp squid, on tenderhooks, mute point etc etc
Thankfully I have never been guilty of any of those ...... But am I the only one that used to proclaim " it depends on how the lamb lies " ?? I only realised my mistake twenty years later after first using it. Whoops !
I blame the classic Gabriel led, Genesis album of 1974 affecting me in my formative years.
