The best man is the chief assistant to the groom at a wedding. The groom usually selects a close friend or relative to serve as the best man, and it is considered an honor to be selected. The best mans role is to serve as the grooms right-hand man throughout the planning process and on the day of the wedding. The best man is responsible for specific duties, which may include:

• Planning and arranging the bachelor party or stag do
• Assisting with picking the suits and wedding day attire
• Helping the groom get ready for the ceremony
• Standing next to the groom during the ceremony
• Keeping the wedding rings safe until needed during the ceremony
• Acting as a legal witness to the marriage and signing the marriage certificate
• Preparing and delivering a "best mans speech" at the reception
• Greeting wedding guests
• Dancing with the maid of honor
• Supporting the groom with all wedding day attire needs
• Completing logistical tasks
• Mingle with guests often and keep the reception alive and moving

The best man is typically the grooms right-hand man and is in charge of the groomsmen, meaning he leads all communication and spearheads most of their activities and duties. The best man is also responsible for creating a real sense of occasion and excitement for the groom and the bridal party. Traditionally, there is one best man in the wedding party, but nowadays, there really are no rules, and its certainly okay to have two or more best men or no best man at all.
