It wasn’t your imagination: Sunday night’s episode of “Mad Men,” aptly titled “The Crash,” was pretty freaking weird.

It seems like other people have noticed that, once the team at Sterling Cooper Draper Pryce (slash Cutler Gleason and Chaough, whew!) injected some Hunter S. Thompson-esque doctor’s stimulant serum to help them power through a weekend on the Chevy account, things got hinky.

The Atlantic’s roundtable recap starts off with “This is your ad agency. This is your ad agency on drugs.” TIME’s Jesse Dorris echoed that and said, “I’ll now drop trou and prepare for Dr. Hecht’s next injection. They make me feel like Peggy felt when Stan complimented her ass: alive.”

Was it when Stan got impaled during a game of William Tell? When “Grandma Ida” terrorized the Draper children? When Ken cane-stepped? When Stan and Cutler raced around the office?

Who knows. This season is set in 1968, the year things started really going sideways in the United States. Maybe the show is just reflecting that sense of WTF.
