"Me," to Miss Piggy (3)
I believe the answer is:
'me to miss piggy' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for moi that I've seen before include "Daniel arap . . ., Kenyan president for 24 years" , "You surely don't mean me?" , "egoist" , "Me (facetiously)" , "it's the writer being facetious" .)
