Game of rugby's finale's being featured in comic strip (5)
I believe the answer is:
goofy
'featured in comic strip' is the definition.
Both the definition and answer are adjectives. Maybe you can see a link between them that I can't see?
'game of rugby's finale's' is the wordplay.
'game' becomes 'go' (go is a board game).
'finale's' indicates one should take the final letters (I've seen 'finale' mean this).
The final letter of 'rugby' is 'y'.
'go'+'of'+'y'='GOOFY'
'being' is the link.
Can you help me to learn more?
(Other definitions for goofy that I've seen before include "imbecile" , "Disney's anthropomorphic white-gloved canine" , "Disney cartoon character" , "Silly -- ridiculous" , "Harmlessly eccentric" .)
