Or; A Portrait of the Baker as a Young Filly.
Finnegan buys a slice of cake from Sugarcube Corner. We think…?
A parody (Pastiche? Mockery?) of Finnegans Wake and A Portrait of the Artist as a Young Man, in that order. I've only read a few paragraphs of James Joyce, so this parody may be is a completely inaccurate waste of time. Go follow Amit if you want fidelity.
