A good friend was getting married and did not ask me to be his best man; the speech that was given by the guy who he did ask was awful, he didn’t even make it about the happy couple.  Think about how long you’ve known your friend, what you’ve done together, what your appreciate about the bride, when you are planning your speech.  If necessary, produce a list of these items before you compose your speech or, if you want to wing it, just hold your essential points on a piece of card so you don’t leave out anything.

This is not a very good best man speech for a wedding and to start, it’s an insult to the bride here  When you get up to render your address, give thanks to everybody for attending before you start to congratulate the bride and your friend the groom.  If you’re a relative, brother, uncle or brother-in-law to the bridegroom, try to speak about the type of character the bridegroom will bring into the bride’s family and talk about them.
Most important thing to remember is how much loving they have for each other.
 
Make sure your best man wedding speech isn’t too long, as you will not be the only guest speaking.  Most likely, the maid of honor, parents of the bride and groom will also want to talk these days and more than 2 parents and stepparents, it is better to preserve its leadership, at least, so everyone has time to talk  Pursuing these tips will guarantee your best man speech is one not to forget so take some time when you make ready it and if you are improvising, use index cards if you want to mention them in your words.
