We doubt the bride and groom were having a good time.
The bachelorette party is expected to be silly and full of pranks, according to the bridesmaids. However, they should get all of the practical jokes out of their system right away and not bring that attitude into the wedding day.
We doubt the bride and groom thought it amusing when they discovered the bridesmaids (presumably with the help of the best men) had vandalised their automobile. Who wants to waste time unwrapping their car from saran wrap on their wedding day?
