Today, as you ponder, "How do I trick this person?," just remember that there is a line to be crossed. April Fool's can go terribly wrong in several ways, and you don't want to be remembered as that douchebag who ruined it for everyone. Please exercise good judgement and common sense. Remember that idiom: It's all fun and games until someone loses an eye. I'm still so sorry, Tyler.
April Fool's! Go fucking crazy.
