  As your friends grow older, birthday parties can seem like less of a big deal. Holding a surprise party for an adult friend is a great way to make a birthday fresh and exciting again. Whether your surprise bash is at an old, familiar hangout or a new, mysterious location and whether it brings together a big tribe of long-lost friends or a few choice companions, the birthday boy or girl will remember the day for a long time.
  
  

Kidnap Birthday Party

• The classic teenage "kidnap" birthday party is a great stunt to play on siblings, best friends and other close adults. With the aid of the birthday boy's spouse or another family member, burst into the house in the morning and "kidnap" the person. Blindfold him and hustle him out of the house in his pajamas and take him out to breakfast. Then, take him to the bar, out bowling or to some other social destination. If you feel like being merciful, bring a change of clothes along for the birthday boy and allow him to change after breakfast.
  
  

Birthday Roast

• Some of the best surprise parties poke fun at or "roast" the birthday girl in a good-natured way. Have a "come dressed as the birthday girl" party, where everyone wears the same sorts of clothes the guest of honor does. Old friends can put on embarrassing outfits or hairstyles from past eras of the birthday girl's life to tease her. Alternately, hold a costume party where the guests all dress as characters from her favorite books, movies and television shows. For even more entertainment, have guests perform skits about the birthday girl.
  
  

Romantic Birthday Party

• You don't have to have a big group birthday party to have a surprise party. Instead, hold a private birthday for the most special person in your life. If you want to keep it at home, prepare a candlelight dinner while she is at work, complete with her favorite food. Alternately, blindfold her and take her to a favorite spot. Bring a picnic basket and a blanket to cuddle on after the meal. For a lavish surprise, tell the birthday boy to take the weekend off, but don't say why. Whisk him away on a surprise weekend cruise.
