I met my fiancée at a bus stop, then proposed to her five years later in the same place. This was our wedding invitation, originally in Flash so people could RSVP through it.
The couple commissioned a comic artists friend of theirs (at http://www.viruscomix.com/subnormality.html) to create a picture of their wedding party. The wedding photographer then had everyone recreate the pose. I think it was done very well.
On the bright side, these guests don't eat a lot. However, good luck being the center of attention at your own wedding!
