Wedding Toasting Help/Advice

My best friend is getting married in less than a week. I am beyond excited for her big day & all of the festivities leading up to Saturday. It should be a really fun week.

Cassie and I have been best friends since elementary school and I am honored that she asked me to be her MOH. However, now I am freaking about writing my toast! I want it to be perfect. I have done some online research to get some ideas, but I still have a mental block as to what exactly I want to say. So I need your help and/or advice.

1. Have you ever made a toast at a wedding? If so, what did you say?
2. What is the best & worst toast you ever heard?
