It’s funny, whichever way you look at it (3)
I believe the answer is:
gag
I believe this is a double definition.
'it's funny' is the first definition.
(I've seen this before)
'whichever way you look at it' is the second definition.
(Other definitions for gag that I've seen before include "Muzzle or silence" , "Censor" , "Muzzle in palindrome form" , "Muffle with slang joke" , "Funny" .)
