Step 1: Remove Ink Pad.

Step 2: Turn the Pad Upside-down.

Step 3: Put Back In.

Step 4: Stamp Multiple Times Until the Remaining Ink Runs Out.

Step 5: Put on Your Victim's Desk.

<p>or maybe you can just change the permanent ink into disappearing ink in the ink pad.</p>
I agree,&quot;ultimate&quot; should be replaced with slight inconvenience
I agree
<p>not very ultimate. I can think of more ultimate things, like cut the pad and splice a couple colors. Swapping the rubber belts to create impossible dates and make it confusing to turn. <br>The people that used these things have OCD or do it because management requires it. Making it impossible to use or getting strange results will go further than this.</p>
