and therefore , out of a passing respect for this tradition , it will not be said of rincewind and twoflower that they became an ice-blue sinewave arcing through the dark imensions , or that there was a sound like the twanging of a monstrous tusk , or that their lives passed in front of their eyes ( rincewind had in any case seen his past life flash in front of his eyes so many times that he could sleep through the boring bits ) or that the universe dropped on them like a large jelly .
