Breaking of the glass is probably the most complicated part of a Jewish wedding. Some say it's to temper the joy, get people's attention; others say it's a symbol that the couple will be rebuilding a new temple in their shared home; others say it's to remember the destruction of the Temple of Jerusalem. You're insulting if you say mazel tov or being a downer if you recite If I forget thee / O Jerusalem. Can't win, really.
Based on the above, it might at least be interesting? All the intricacies of it all, waiting to be explored.
