Personally, this one:

-The newlyweds had theoretically been together for 5 years but saw each other so little that they were almost strangers to each other.
-The bridegroom discovered only belatedly that the one he was going to marry was a spoiled child submissive to her mother.
-The groom wanted children and the bride said she would think about it, but still hadn't made up her mind on the wedding day.
-Everyone was originally supposed to sleep at a friend's house, who suddenly put the dishes in the big ones, but the mother of the bride decided on a whim that no, her daughter would not sleep in said house, although obviously without notifying the owners.
-3 people (the bride, her mother and a guest) ended up spending the night in the village hall. The mother slept glued to her daughter and the guest had to stay awake all night for lack of a place to lie down.
-During the feast, the guests were of different origins and gathered in homogeneous ethnic groups who stared at one another.
-The DJ only played Senegalese music, which obviously only appealed to guests of Senegalese origin.
-The mother of the bride has a disconcertingly fragile ego, preferring to refuse to answer a question rather than admit that she does not know.
