** How come Mr Bent came to the bank aged 13, stayed for thirty nine years, and yet is specifically said to be in his mid to late forties by characters who should know? WritersCannotDoMath?
*** When is that stated? Moist very clearly states once that he's 52.
*** I can't remember for certain, but I'm pretty sure that it's just mentioned that he ''appears'' to be mid to late forties, which by no means is a certain statement of his real age.
*** Corgi Books 2008, paperback with a 25 years of Discworld sticker , Moist says "he's forty seven" some pages after the mention of thirty-nine plus thirteen. Probably an error that got past editing.
*** Or Moist isn't able to do math as quickly as Bent, certainly not when his mind is otherwise occupied.

** If there are Ankh-Morpork coins worth a fraction of a cent, doesn't that spoil Arnold Sideways' favorite begging technique of asking people "Do you have change for a penny?"
