Yeah the only thing saving Rick here is his fourth wall awareness and knowing Doctor Who lore. Or Mr. Frundles if that's considered standard equipment for him which I don't think it is, it was just something he found.
The Doctor is one of the most terrifying people to face in fiction if he gets serious. And Rick is enough of a douche to potentially piss The Doctor enough to really fuck Rick over.

The Doctor's last words to Rick before he atomizes him:
"You say you explored the universe and that you found no meaning? Well I have a secret, well I guess it isn't a secret since you say you know everything about me. Then you should what I have experienced. I have seen conflict, genocide, famine, and treachery. I've witnessed death and disease. I've held dying friends in my hands. I've went through wars and calamities and do you know what I have to say for all this tragedy? I love this universe. It has meaning. I have seen generosity, reciprocity, kindness. I've seen festivities, and medicine, and cooperation. I've seen marriage and graduations. I've seen the miracles of this universe and in the face of all of this you dare say this universe has no meaning? If you believed this then you are mistaken, but that you challenged me on it you are truly foolish. You've also ANGERED ME!"
