Strange how Humpty Dumpty ended up (3,3,4)
I believe the answer is:
off the wall
I believe this is a double definition.
'strange' is the first definition.
(I've seen this before)
'how humpty dumpty ended up' is the second definition.
(Humpty Dumpty had a great fall)
(Other definitions for off the wall that I've seen before include "Left field" , "Humpty Dumpty's downfall was so" , "Mad" , "how Humpty Dumpty ended up" , "American eccentric" .)
