I know Rick definitely just referred to Rickbot as Morty's toaster as a petty insult, but I like to imagine that it's really because Morty loves toast, so Rick's idea of his ideal babysitter would also double as a toaster somehow... Maybe he tried to pass it off as an implant or something.
Just in case they were out and about and Morty forgot to pack a snack, idk.
Morty: Damn, I'm hungry... :(
*fresh toast violently springs out of Rickbot's abdomen involuntarily*
it's always "do you think god knows youve been sneaking out of heaven?" and never HOW was sneaking out of heaven? did you have FUN sneaking out of heaven?
