A man so rapped up in his fantasies during boring work he started thinking it was all real. (Well, it's a book really)
Later 'translated' into a wonderfull movie with old-time great Danny Kaye.
In fact we have a friend who we call 'Mitty' cos he makes up stories - he's 47yrs old by the way
but he does makes us laugh with his daft stories even though we know they're mostly not true.
Occasionally though when I've caught him out with a lie I tell him I know he's giving us some old bull**** and he just shrugs his shoulders and laughs
