Yeah, but the quote says "her" - that's not him is it? So it must be the one who wrote Wise Blood.
Yeah it was a (very poor) attempt at humour. Never mind.
I really liked At Swim Two Birds - I didn't know that he wrote many novels, I had it in my head that most of his writing was columns and essays and the like for some reason.
I think he wrote five in total - I've got them in a collected volume. Hard to say which I liked best.
The Poor Mouth is very funny, much less well known than his two biggies for some reason. It's an affectionate parody of these very serious and dour novels about picturesque rural poverty that were apparently popular in Ireland at the time, and were usually written in Irish, as
TPM was originally (the English version isn't by O'Brien, it's a translation by someone else). It's about this poor fatherless boy growing up with his mother in rustic squalor in the middle of nowhere. They live with all their animals in this very basic one-room house, and it's incredibly dirty and smelly because of the animals, so one of the neighbours suggests they build a lean-to. They scrape together what meagre funds they have to pay a builder to build a lean-to, but after a while they give up on it "because they found it to be terribly draughty, so they eventually joined the animals back in the main house" (or words to that effect). It's full of stuff like that. There's also a lot of pisstaking of these very serious Irish-language enthusiasts, who are all very middle-class and live in the nice parts of Dublin.
The Hard Life is good too, and is also about a troubled boyhood. The narrator's brother is this precocious boy genius, and when their uncle falls ill, the brother prescribes him a home-made potion called "The Gravid Water". Initially it seems to work but it turns out to have the side effect of serious weight gain. However the uncle doesn't get any physically fatter, he just gets more and more
dense, until he's so heavy he falls through the stairs in their house.
There's also
The Dalkey Archive, which is probably the weakest of the five although still entertaining. Its characters include De Selbey, familiar from the footnotes in
The Third Policeman, as well as (not very flatteringly) James Joyce.
