Getting old, like Bugs Bunny? (4,2,3,5)
I believe the answer is:
long in the tooth
'getting old' is the definition.
'long in the tooth' can be an answer for 'old' (I've seen this in another clue). I am not sure about the 'getting' bit.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for long in the tooth that I've seen before include "Rather old" , "Been around" , "indication of the need for cosmetic dentistry?" , "Getting on a bit" , "Was a woolly mammoth" .)
