One thing I like to do is visit technical forums and ask for help regarding an entirely fictitious problem I'm having with my software. When I receive help, I say, "Nope. Didn't work." If they guide me to a button to click, I say, "Nope. Can't see it." Sometimes I just reply with nothing but "Nope", and it drives them up the wall. But what's mind-blowing about that? I just made it up. It never happened, there is no forum. Yet just the thought of annoying these non-existent people makes me smile. That's next-level trolling right there.
