Chapter II.2 follows Shem, Shaun and Issy studying upstairs in the pub, after having been called inside in the previous chapter. The chapter depicts "coaching [Shaun how to do Euclid Bk I, 1", structured as "a reproduction of a schoolboys' (and schoolgirls') old classbook complete with marginalia by the twins, who change sides at half time, and footnotes by the girl (who doesn't)". Once Shem (here called Dolph) has helped Shaun (here called Kev) to draw the Euclid diagram, the latter realises that he has drawn a diagram of ALP's genitalia, and "Kev finally realises the significance of the triangles [..and..] strikes Dolph." After this "Dolph forgives Kev" and the children are given "assignments on 52 famous men." The chapter ends with the children's "nightletter" to HCE and ALP, in which they are "apparently united in a desire to overcome their parents."
