George's firearm I found in bed (9,5)
I believe the answer is:
automatic pilot
'george's' is the definition.
(George can informally mean a plane's autopilot sys)
'firearm i found in bed' is the wordplay.
'firearm' becomes 'automatic' (automatic is a kind of firearm).
'i found in bed' becomes 'pilot' (I can't explain this - if you can you should believe this answer much more).
'automatic'+'pilot'='AUTOMATIC PILOT'
Can you help me to learn more?
(Other definitions for automatic pilot that I've seen before include "Device keeping aircraft on course" , "George" .)
