It's thrown in sad picture? Yes and no (7,3)
I believe the answer is:
custard pie
'yes and no' is the definition.
I can't judge whether this definition defines the answer.
'it's thrown in sad picture?' is the wordplay.
'it's thrown in' is an anagram indicator (the letters must be thrown around).
'sad'+'picture'='sadpicture'
'sadpicture' is an anagram of 'CUSTARD-PIE'.
Can you help me to learn more?
(Other definitions for custard pie that I've seen before include "It's thrown for laughs" , "Slapstick missile" , "But is one thrown" , "What featured in comedy" , "Element of slapstick" .)
