Takes a bit longer to setup...
Blow cress-seed under the door of someone who has a fairly deep pile (but not wooly) carpet when they're away for the weekend. Then pour/blow some water through and leave.
Cress can grow at an incredible rate on just about anything, so with any luck, he'll come back to a nice cress lawn... and worse still, once the roots take hold, u can't vacuum them up - he'll have to mow it regularly!
