Pretend to doze, but every so often reach out and slap the pencil or pen. First, sit on the paper being worked on. When dislodged, watch sadly from the side of the table. When activity proceeds nicely, roll around on the papers, scattering them to the best of your ability. After being removed for the second time, push pens, pencils, and erasers off the table, one at a time.
Humans love to jump.
This will help their coordination skills. When using the litter box, be sure to kick as much litter out of the box as possible. Humans love the feel of kitty litter between their toes. Every now and then, hide in a place where the humans cannot find you. Do not come out for three to four hours under any circumstances.
