Walk up to a complete stranger.
Ask him how he is doing.
Talk to him like you have known him a long time.
If he calls you on the fact he doesn't know you from Adam, just laugh.

After you are done with the pleasentries, lean close to him and whisper this in his ear...

"They are in the vacuum cleaners. They eat the dirt. They grow strong on it. Soon they will unite and take over the world."

The guy should ask you who?

You say, "The Dust Bunnies" and start to laugh like a madman and skip away.

Don't walk, don't run.

SKIP.
