After choosing the groomsmen, you're going to have to pick one of them to be your best man. Most men don't lose a lot of sleep over this issue, but if you have three best friends to choose from, it could be a tough call.

You've got to have a best man — there's no way around it. One way to narrow down your options is to realize that the best man is actually responsible for quite a few things:

He's supposed to organize your bachelor party.

He should help you corral the other groomsmen into the tux shop.

He should help you supervise the other attendants on the wedding day.

He needs to get you to the church on time.

He's responsible for hanging on to the rings, the marriage license, and the officiant's fee.

He gives the first toast at your reception.

The best man is tasked with standing by you throughout the wedding season. Make sure you choose someone who is up to the challenge. If you're choosing from several friends and only one of them is adult enough to handle these tasks … your choice is easy.

Some men choose their dad to be the best man. You might want to think twice about this, especially if the rest of your wedding party is following a standard route. Is your dad really going to feel comfortable spending the day with your rowdy pals? Is he really going to host the kind of bachelor party you want? Would he rather sit with his wife at the reception than at the head table?

If your wedding is small, your dad might feel very comfortable playing the role of best man. Otherwise, let him opt out. The same advice applies if you're thinking about asking your child to fill the role.
