We first argue that the Fregean treatment of I-thoughts entails that they are what we call “one-shot thoughts”: they can only be thought once. This has the surprising consequence that no instance of the “a=a” form of judgment in this specific case comes out true, let alone a priori true. This further reinforces Glezakos’s objections against the set-up of Frege’s puzzle, while also raising what we think is an acute problem for Fregeans, insofar as I-thought (and indexical thinking more generally), understood in their way, turns out to be incompatible with some basic features of rationality. %Z This is an Open Access article published under the terms of the Creative Commons Atribución-NoComercial-CompartirIgual 3.0 Costa Rica Licence (http://creativecommons.org/licenses/by-nc-sa/3.0/cr/).
