This one requires a bit of planning, and a very messy friend. You’re at your messy friend’s apartment. Somewhere towards the end of the night, you notice that he’s so messy, he hasn’t made his bed. Taking special care to sneak into the bedroom, lock the door behind you. Then, make his bed. But don’t just make his bed. Make his bed like they would at a hotel, taking extra special care as to the uniformity of the folds of the sheet, the plumpness of the pillows, etc. Then, place a mint on his pillow. This is perhaps one of the most baffling pranks you will ever commit.
Very Important Business at the other end of the room.
At a crowded holiday party, notice a friend standing at the opposite end of the room. Make eye contact with him, and urgently begin to beckon him over. Once this friend has spent a good ten to fifteen minutes getting to your position, pretend to forget what you wanted to talk to him about, or else shrug and say “Oh, never mind… It’s not that important.” Then, once he’s back at the other end of the room, do this again. Repeat five or six times, or until you’re punched.
This trick works best if you 1) have strong prescription glasses, and 2) have had three or four drinks. (If you have glasses, remove them. If you don’t have glasses, squint really hard.) At a crowded party, scan the room for somebody who looks remotely like somebody else that’s famous. For example, your grandfather could be Henry Kissinger. Your aunt could be Meryl Streep. Your best friend could be Chace Crawford. Then, make a very big deal about this, proclaiming quite loudly while pointing “Oh my WORD! It’s Henry Kissinger!!” Be very insistent, asking questions about his work with China during the Nixon administration, even if he insists that he is not, in fact, Henry Kissinger.
