Embarrass Your Bestie
The trick to thinking up the perf April Fool's prank is knowing the person really well -- so your bestie should be a cinch! You know her better than you know yourself, right? Figure out what she's most stressed out about and then use it to your benefit. Is she totes obsessed with a guy you know? Get a hold of her phone when she leaves the room and switch his number with yours. So when she calls and texts you to dish, he'll get all the messages. She'll be so confused when she hears his voice when she's trying to get you on the phone!
