Congrats! You are the best man, universally acknowledged from this point on as not just the man but the BEST man. Secretly you’ve known it all along but it's still nice to get the rightful acclaim. However while you might wear the badge you now have to live up to the title. There’s the stag party to plan, you have to look after the groom, take charge of the ushers and then of course there is that speech. But worry not fine Sir, we've got your back Jack. The Best Man-ual is the definitive guide to being the best man.
