Like the thing there? Well I never (5,4)
I believe the answer is:
fancy that
'well i never' is the definition.
(both are expressions of disbelief)
'like the thing there?' is the wordplay.
'like' becomes 'fancy' (both can mean to find someone attractive).
'the thing there?' becomes 'that' (I can't justify this - if you can you should believe this answer much more).
'fancy'+'that'='FANCY THAT'
Can you help me to learn more?
(Other definitions for fancy that that I've seen before include "Gosh" , "goodness" , "Well I'm blowed!" , "exclamation of surprise" , "Imagine!" .)
