Bachelor parties are a fun way to celebrate the upcoming marriage of a friend, family member or associate. While some bachelor parties contain more adult fun, it is possible to host a bachelor party that is appropriate for the office as well. To add to an office bachelor party, consider playing these games with the bachelor and co-workers.

Set up an office conference room for a bachelor video game tournament that can take place either during lunch or after work. Bring in two or three televisions and different gaming consoles so multiple co-workers can play at once. You should bring different types of office-friendly games like "Madden NFL," "Wii Sports" or "Michael Jackson: The Experience." Be sure to invite as many people as possible to participate to increase the fun.

Set up a dart board in an office conference room that the bachelor and co-workers can all play. Take turns aiming for the bull's-eye with your co-workers or set up a "best of" scenario. Make a rule that whoever has the least amount of points at the end of the game has to buy the entire office lunch. Give away a $5 Starbucks gift card to the winner as a prize as well.

Set up a trivia game competition for the bachelor and co-workers to play. Games like Taboo, for instance, are fun and build teamwork in the process. You may also play sports or car trivia games that test everyone's knowledge of those subjects. If women are at the party, a battle of the sexes trivia game can be fun to play at work as well. You may also create teams based on departments everyone works for. For example, have the Accounting department compete against the Marketing department.

If your office building has a gym, a game of H.O.R.S.E. can be a fun addition to any bachelor party. This game requires that players try to make shots that the previous player just made for points. If a player misses a shot, he will acquire a letter until they spell out "horse." At which point, he is out. To incorporate your "office" theme, use your boss's name or the company name to create the game letters. For instance, play "A.L.E.X." if that is your boss's name.
