The Paris Olympics opening ceremony has it all, and people are... processing.

The ceremony, billed as one of the most ambitious ever, featured a parade of boats along the Seine, with a series of fun and quirky shows along the banks as well as some prerecorded segments. It replaced the typical format of a parade of nations inside a stadium.

Athletes, some wearing ponchos over their uniforms, kept their spirits high despite rainy weather, waving from their boats.

Lady Gaga stunned with a very va-va-voom rendition of Zizi Jeanmaire’s “Mon Truc En Plumes” on a set of stairs by the river, surrounded by enormous plumes of pink feathers.

In another segment, headless women dressed in red — representing the ill-fated queen of France, Marie Antoinette — appeared in the windows of a grand building amid bursts of fire and an energetic performance by heavy metal band Gojira. This was followed by opera music.

Elsewhere, dancers in pink, including a woman dressed as a croissant, partied in the streets. There was also a catwalk showcasing out-there French designs. Also, Minions. And in one prerecorded bit, apparently the beginning of a ménage à trois?

Throughout the show, viewers were shown clips of a hooded figure carrying the Olympic torch, leaping and bounding across Parisian rooftops, in a nod to “The Phantom of the Opera.”

Some viewers were delighted by the French-ness of it all. Others took issue with the boat parade format. Some simply had no idea what was going on.

“WHAT IS GOING ON,” one user wrote, sharing a clip of the Marie Antoinette moment.

“A beheaded Marie Antoinette is one of the wildest and craziest things ever at the Olympics,” said another.
