When someone is supposed to be writing something and isn't, yet leaves one tab open in his/her browser that relates to what he's supposed to be doing, making it appear as if the person is actually doing something. I'm doing it right now
Person 1: Isn't John supposed to be writing a cross-analysis on the early philosophers? Why are all these facebook and youtube pages open?

Person 2: But look, his current tab is a Wikipedia entry on Plato

Person: Wow, I can't believe you fell for the tab illusion
