Clearly Artemis is using the Alanis Morrisette brand of 'irony', which as any fule kno is almost wholly antithetical to the classical definition of irony.
That it was Morrisette irony was signalled by his use of the the phrase 'a lil bit ironic, dontcha think?' which is of course a lyric from Miss. Morrisette's ironically entitled song 'Ironic'.
