Okay, so I'll admit I've watched this show, but not in the past couple months. On slow days I'd watch CN, but other than Steven Universe, I barely watch television anymore. But for some reason, this scenario came in to mind the other day.

Anyway, they goofed off again, and realized how late they were for, something or other, but Rigby didn't get a chance to relieve himself before they left. So he's gotta hold it for who knows how long. And they pass a portable toilet on the way.

This sketch was a bit of a challenge ^^; The cart, the angle, keeping the characters recognizable without resorting to tracing or anything like that. Had to redo Rigby like 4 times. Overall, not entirely satisfied, but if I tried any more I'd ruin it ^^;

Well, enjoy, I guess.
