Wedding Invitation Wording

I need help... I`m getting married in July 2006. It`s going to be a civil wedding but we`re treating it like a chruch wedding. We have a funny invitation-a cartoon drawn wedding invitation and I wanted to put the wording in a not so serious manner but also not too child-like. There will be a chruch wedding and tha`ts where we`ll get serious. So, if anybody can tell me anything, please... It is highly appreciated.
