Bachelorette
Host a bachelorette party where each scavenger team finds something old, new, borrowed and blue, in keeping with bridal traditions. The website Bachelorette Wedding Ideas suggests assigning players to locate and photograph a man who resembles the groom. Have your friends snap photos of the entire team on a dance floor, in front of a bridal boutique and inside a phone booth as they make a prank call to the groom. Expect each group to return with photographic proof that they asked a stranger for his telephone number.
Answers
Dispatch your friends on a quest for answers. For instance, ask them to return with a description of what films are playing at a nearby theater or a list of flavors at an ice cream parlor. Include a request for details on the new exhibit at the museum. Give them a two-hour deadline. Confirm all the answers to your scavenger hunt questions in advance of the party. Assign points based on each question's level of difficulty, and give party prizes to the winning team.
Mall
Send your friends to a shopping mall with requests that they capture silly exploits on film. For example, require a group to squeeze into a restroom stall, try on purple eye shadow at a cosmetic counter and offer snacks to food court patrons. Assign another crew to purchase something for 99 cents, assist a shopper with her packages and pose as store mannequins near a window display. Send teams to separate malls with the same list, or use one shopping facility with different scavenger items.
Local
Assign each team a different series of objects that they can find within a short distance of your home. Ideas include napkins from a nearby fast-food joint, a bank deposit slip, a Chinese restaurant menu and a photocopy of a hand. Or, lend a video camera to each team so they can return with footage of themselves helping someone pump gas at a local service station, standing near a community monument and riding a tricycle.
