Celebrate a 50th birthday by planning a party with a theme that relates to the birthday guest's interests, such as his favorite color, a band or television show he likes, or costumes related to a specific time period. Incorporate the number 50 into the food, decor or party games.
Invite the birthday guest's friends and family to the party, and make sure the venue has enough space to accommodate everyone. Locations for a birthday party include the party planner's home, the birthday guest's home or a rented room at a location such as a golf club or church. Ways to incorporate the number 50 into the festivities include inviting 50 guests, decorating with 50 balloons or putting 50 pictures of the birthday guest on a wall.
During the party, toast the birthday guest by having each person say one funny thing about him. Theme party examples include a masquerade ball or a band party. For a masquerade ball, decorate the room in a style similar to the early to mid-19th century, and tell all the guests to wear vintage clothing. Supply masks for everyone to complete the setting. For a band party, get posters of the birthday guest's favorite band to decorate, and set up a music playlist with all his favorite songs.
