In their brief time together Slothrop forms the impression that this
octopus is not in good mental health, though where’s his basis for
comparing? But there is a mad exuberance, as with inanimate objects
which fall off of tables when we are sensitive to noise and our own
clumsiness and don’t want them to fall, a sort of wham! ha-ha you hear
that? here it is again, WHAM!
—-Thomas Pynchon, Gravity’s Rainbow
