Half-hearted attempt at patriotism

Finn was rather non-plussed at the thought of dress-in-green-day in school... 

Yeah, roight. Non-plussed his shamrocky arse. 
He went to school dressed in green from head to toe, proud as punch, singing a rather jolly-sounding Irish song (strange, they usually sound guttural and gloomy in equal measures).

You look good in green, Finnzy-Bob
