Wait until the lucky person is eating dinner on the special day
Show up at their house unannounced and greet them with “[your name], at your service” and just walk up in there and join them for dinner.
Have your friends show up one by one or in pairs and do the same (works best with at least 13 people, obviously).
Once seemingly everyone’s there and your friend is appropriately overjoyed yet horrified because they weren’t prepared to host guests, there’ll be a knock at the door and all of you will fall silent while one of you ominously says “he is here”, opening the door to reveal the final guest who should arrive with pizzas and/or cake.
Congratulations, you now have an actual Unexpected Party.
(P.S. Cosplay is not mandatory but highly recommended)
(P.P.S. At some point, you should all break out into song without warning, preferably to “That’s What Bilbo Baggins Hates”)
“He was quite content; and the sound of the kettle on his hearth was ever after more musical than it had been even in the quiet days before the Unexpected Party; because he had bought a really fancy kettle with all of his money. He loved being so incredibly rich.”
The Hobbit, an unexpected feast! Please don’t tell me I’m the only one that wants to party hobbit-style?! I’m going to use this image as the inspiration for my next dinner party with the gals. Last time we deep-fried a whole bunch of random stuff; this time, Hobbit Party, baby!

“All of them at once,” said Bilbo. “And a very fine morning for a pipe of tobacco out of doors, into the bargain. If you have a pipe about you, sit down and have a fill of mine! There’s no hurry, we have all the day before us!”
