I find it noteworthy that one of them reached the 'explanation' before the other, despite them having identical minds. Although I recognise that the comic is fiction, it made me wonder if there is a degree of randomness in thought processes for whatever reason, be it in the chemical transfer between synapses or something else.
I think its also rather likely that both of them honor speaking conventions to a large degree. Thus, even if they both came up with the same conclusion at the same time, only one of them stated it, because it was his turn to talk. Either that or we would have to say that the cafe down the street is more conducive to revelatory thoughts, and also lesbian milfs.
Hmm... making out with oneself...If you do (did) that, then swb, next time when someone tells you to go fcuk yourself, you can proudly say, "Hey! I did it, ya know!"Imagine, you will be the only dude in the world of dudes who can proudly claim this!
