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.

A discreet way to leave the table at a restaurant to go to the restroom; derived from a 1940's black-and-white film (sorry, cannot recall the name) where an actor literally says it as he leaves a table to see a man at another table about a horse.

"Excuse me, I have to see a man about a horse."

The origins date back to the days of the "Not-Quite-So-Wild-Yet-Still-Wild Enough Old West". When at the local drinking establishment (read at the Saloon) the horse trough was closer to the entrance of the building (usually directly attached) than the outhouses which were generally situated out back. And thus a slang term was born. And of course MOST people had enough common decency to only use the trough for number one.
Excuse me, I suddenly feel the urge to see a man about a horse.
