Another great line of explanation, this one for when somebody accuses you of behaving idiotically. It's the Occam's Razor of excuses: simple in the extreme, plausible, and probably true. "Was I drunk?" Here's an example of its use.
Somebody: Remember the time you did something stupid?
You: Was I drunk?
It works. Embarrassing discussion halted in its tracks. Now, thanks to rickyH, I even have the means for shutting even the most annoying pie holes on virtually any front. The Babylonians took it, did it, started it, ate it, supplied the liquor, used the last of the toilet paper, killed Kennedy, killed Kenny...all of it. And if it wasn't the Babylonians, it was probably the Adultlonians.
