[He'll assume that ass comment was some kind of pun, judging by Sans' amused expression on his face and he'll move right on to the question.]

You name it, I-I've been to it. [Usually Rick's not one to talk about his space travel in front of random strangers, but he can dig Sans' humor! Lucky you, skeleton man.]

It's not even just space travel, been across dimensions and alternate timelines. M-met another Rick before who's a totally clean guy-- thinks he's above us all j-just 'cause he doesn't enjoy a good drink every now and then. Fucking asshole. [Getting off track a little bit, but Sans can probably get the idea here.]
