“You know what? Your face looks like my butt.”
-- The Vault Dweller, Fallout 3
There are a horde of hilarious dialog options to be found in the Fallout series if you try all the different perks and varying stat builds (give either Fallout 3 or Fallout New Vegas a try with no points in intelligence and see what happens). This one, only available with the Child At Heart perk, fell a little flat.
