go to the bathroom.

While it may be used in "Finding Nemo", Mr. Disney (who was deceased, by the way, when "Finding Nemo" was made) did not come up with it. It is an Austrailian saying which was popularized in the movie "Crocodile Dundee".
"Man, that was a great chili dog, but now I've gotta see a man about a wallaby."

Get the see a man about a wallaby mug.
Take a crap, drop a bomb, drop some friends off at the pool, feed the porcalin, brown the water, kill a potatoe, make a deposit, feed the chickens, chop the firewood, weed the lawn, attack the castle, make an appeal, go windsurfing, see a movie, write an english paper, farfegnuegin, or make some chocolate. If you are confused, we're talking about pooping here.
The wallaby one is honestly from a Disney movie, "Finding Nemo". Man, Disney, good call!
Excuse me, I have to go see a man about a walaby. Keep rinsing, we'll start on the back molars in just a few.
