1.  Keep it short and sweet - 30 seconds to 3 minutes.

2.  Keep it clean.  Stay away from stories involving partying, getting it on, or embarrassing moments.  No dirty or crude jokes.

3.  Speak from your heart.  Tell an endearing story of the couple’s courtship.  Avoid long winded stories about childhood.

4.  The couple’s personality, family, and ceremony set the tone.  Keep in mind how conservative and/or religious the couple and their families are.  If the ceremony and reception is very formal, leave the jokes at home.  When writing your toast, keep these three items in the back of your mind.

5.  Relax.  It can be nerve racking to be the center of attention and make a meaningful speech in a room of virtual strangers.  Stand up, speak in a clear, even tone, avoid "um(s)" and using the word "like" repeatedly, hold the microphone at your chin, annunciate your words, and make eye contact with different guests across the room and the happy couple.

Good luck!
