e-mailroulette
Opening an e-mail and its attachments like you're begging for trouble in front of your entire class.
You open a file called 'Important_Project. ppt' in front of your group. It was a virus. You're now the group's embarrassment.
Your mom sends you a link to a 'cool meme.' You click it. It turns into a 10-minute video of a cat falling off a building.
You open an e-mail from a guy who claims to be a billionaire. It was a scam. Your face is now the definition of 'what the hell?'.
