All good political cliches can be used as euphemisms for going to the bathroom.

"I've got to go stay the course."
"Time to support the troops."
"I'm going to look for weapons of mass destruction, back in five..."

Hmmm.... I think he's got something. For the next month, we're going to be inundated by these lame phrases, so we might as well fight back by using them as potty-euphemisms:

I'm going to flip-flop on a major issue.
I'm heading for an undisclosed location.
Time to report for duty.
I need to build a coalition.
I'm about to make the world a safer place.
I'm gonna turn the corner.

Of course, when you come back, you can announce, "Mission Accomplished!"
