What's the longest line you've ever encountered? I just remembered this banger from Salman Rushdie's The Satanic Verses, lol:

'Once I'm an owl, what is the spell or antidote for turning me back into myself?' Mr Muhammad Sufyan, prop. Shaandaar Café and landlord of the rooming-house above, mentor to the variegated, transient and particoloured inhabitants of both, seen-it-all type, least doctrinaire of hajis and most unashamed of VCR addicts, ex-schoolteacher, self-taught in classical texts of many cultures, dismissed from post in Dhaka owing to cultural differences with certain generals in the old days when Bangladesh was merely an East Wing, and therefore, in his own words, 'not so much an immig as an emig runt' — this last a good-natured allusion to his lack of inches, for though he was a wide man, thick of arm and waist, he stood no more than sixty-one inches off the ground, blinked in his bedroom doorway, awakened by Jumpy Joshi's urgent midnight knock, polished his half-rimmed spectacles on the edge of Bengali-style kurta (drawstrings tied at the neck in a neat bow), squeezed lids tightly shut open shut over myopic eyes, replaced glasses, opened eyes, stroked moustacheless hennaed beard, sucked teeth, and responded to the now-indisputable horns on the brow of the shivering fellow whom Jumpy, like the cat, appeared to have dragged in, with the above impromptu quip, stolen, with commendable mental alacrity for one aroused from his slumbers, from Lucius Apuleius of Madaura, Moroccan priest, AD 120-180 approx., colonial of an earlier Empire, a person who denied the accusation of having bewitched a rich widow yet confessed, somewhat perversely, that at an early stage in his career he had been transformed, by witchcraft, into (not an owl, but) an ass.
