Where one may be bitten by the performing bug? (4,6)
I believe the answer is:
flea circus
'where one may be bitten' is the definition.
I know nothing about this answer so I can't judge whether this works.
'by the performing bug?' is the wordplay.
'by' means one lot of letters go next to another.
'the performing' becomes 'circus' (I can't justify this - if you can you should believe this answer much more).
'bug?' becomes 'flea' (I've seen this before).
'circus' after 'flea' is 'FLEA CIRCUS'.
Can you help me to learn more?
(Other definitions for flea circus that I've seen before include "Show using insects" , "where creatures perform" .)
