Fry: Bathroom's that way. [guy gives a grateful look and runs off]
One of the first actions most people undertake upon awakening is to relieve themselves, largely because the kidneys are still hard at work even during sleep. Despite the fact that you can't exactly hydrate in your sleep, you're still going to end up with something to get rid of. If your bladder is full after a night's sleep, just think how much worse it would be after being Asleep for Days, or at least decades. Writers will sometimes milk this for comic potential by having a character be awoken from, say, a magical sleep lasting a hundred years, or even being dead, be in desperate need of a bathroom. But don't worry; this trope rarely ever ends in a Potty Failure.
It doesn't have to be that; suppose you weren't asleep at all, but just incapacitated/trapped somehow. Conscious or semi-conscious, the results still feel the same to you.
A much more mundane version of this trope would be simply Potty Emergency.
- Related but squicky example in Dragon Ball Abridged. After spending a month on a spaceship with Bulma walking around in her underwear the entire time, Krillin has had no opportunity to... relieve himself, especially because the toilet keeps screaming at him. Once they finally land on Namek, Krillin excuses himself and heads into a nearby cave to "take care of business", then leaves with Gohan. Then Bulma goes into the same cave to set up camp and... "OH GOD, IT'S EVERYWHERE!"

The new "statue" is holding its crotch in agony, implying that this trope will come into play if he is ever unfrozen again.
