Tape a photo of Nic Cage, Shrek, or whoever else you want to the top of the copier.
贴一张尼古拉斯凯奇或者史瑞克或者任何你想放到复印机里的人的照片。
You'll want to place it opposite the side where people usually place their paper so that their paper doesn't cover it entirely. With proper placement, hopefully Nic's crazy eyes will be peering just over the bottom edge of their document.
最好放在人们经常放纸的另一侧，这样他们要复印的文件就不会完全盖住照片。只要找到适合的位置，很有希望在复印出来的文件底部看到尼克的眼睛在凝视你！
