The best man speech is often discussed and debated. Should the speech be a heartfelt, mostly impromptu speech? Should it be a meticulously planned tribute to your friend, the groom? The answer is that a good best man speech will lie somewhere in between the above two extremes. First, make sure, as the best man, that you explain your relationship to the groom - many in the audience may not know you were college roomates for 4 years. Plan the most important points you want to share so you don’t miss any. Try to use humor in the form of a true anecdote or tell a joke that is personalized so it seems like a true story about the groom.
