Dave is Damon's co-worker and ex-roommate. He works in the web design part of Resolution Systems.  Dave is married to Sara. Damon was in Dave's wedding. Many people think that Dave looks like Bill Gates. So when you think you see Bill Gates standing up for Damon, it is really Dave. But if you continue to think that Bill is at our wedding, that is just fine. However, I don't think that Bill Gates would wear a kilt.
