Help! We Want A Funny And Original Wedding Party. Ideas?

Well, we are finally starting to plan for our wedding which will be at some point over the Summer/Fall. We are hoping to do an outdoor wedding with party tents, etc. The invitations are already designed as if our baby son is the host of the event.
We would like to come up with a very funny and original wedding party (for 100 people) as that is our nature - humor. Any help would be most appreciated
