Foolishly threaten cop? You might find yourself here (2,3,6)
I believe the answer is:
on the carpet
'you might find yourself here' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'foolishly threaten cop?' is the wordplay.
'foolishly' indicates anagramming the letters.
'threaten'+'cop'='threatencop'
'threatencop' anagrammed gives 'ON THE CARPET'.
Can you help me to learn more?
(Another definition for on the carpet that I've seen is " Severely reprimanded by someone in authority".)
