Another day, another false alarm from the president — and then a welcome stretch of comic relief on Twitter.

Donald Trump’s apparent assertion at a rally Saturday that something tragic had happened the previous night in Sweden had everyone scratching their heads.

“You look at what’s happening in Germany, you look at what’s happening last night in Sweden,” he said, passionately but inexplicably. “Sweden! Who would believe this?”

No one could believe it — not even Sweden, whose officials contacted the White House to find out what the president was talking about. Former Swedish Prime Minister Carl Bildt asked what Trump had been smoking.

Sweden? Terror attack? What has he been smoking? Questions abound. https://t.co/XWgw8Fz7tj — Carl Bildt (@carlbildt) February 19, 2017

Which led to this:

Trump clarified Sunday that he was referring to something he had seen on Fox News ― apparently an interview with conservative filmmaker Ami Horowitz, who linked a purported rising crime rate with the thousands of refugees Sweden has welcomed to its country. The nation took in more refugees per capita than any other European country in 2015. Crime rates in Sweden have changed little over the past decade, The Guardian reports.

My statement as to what's happening in Sweden was in reference to a story that was broadcast on @FoxNews concerning immigrants & Sweden. — Donald J. Trump (@realDonaldTrump) February 19, 2017

We look forward to informing the US administration about Swedish immigration and integration policies. https://t.co/x5G3euOWRh — Embassy of Sweden US (@SwedeninUSA) February 19, 2017

It was all great fuel for the Twitter fire that erupted, with snarky rejoinders at #LastNightinSweden, #PrayForSweden, #SwedishIncident and #IStandWithSweden. Critics especially enjoyed juxtaposing Trump’s suggestion of a terror attack against the reality of a pretty, tranquil, sometimes even downright dull Sweden.

Author J.K. Rowling got in on the fun after Swedish news reported that the big story in the country on “terror day” was the rescue from a well of a horse named Biscuit.

There were the inevitable quips (including one from former first daughter Chelsea Clinton) referring to Trump aide Kellyanne Conway’s mention earlier this month of the nonexistent “Bowling Green Massacre” and White House spokesman Sean Spicer’s reference to a nonexistent terror attack in Atlanta. The man the president spoke so glowingly of earlier this month, the late Frederick Douglass, purportedly returned from the grave to protect Sweden.

What happened in Sweden Friday night? Did they catch the Bowling Green Massacre perpetrators? — Chelsea Clinton (@ChelseaClinton) February 19, 2017

For all those involved in the incident #LastNightInSweden the thoughts & prayers of the Bowling Green Massacre Survivors Group are with you. — Redford King (@RedKingsRace) February 19, 2017

Sweden terror incident is the largest attack that never happened in Swedish history. This travesty will never be remembered. #SwedenIncident — Cameron Stell (@cameron_stell) February 19, 2017

There had to be some comments about Ikea, of course.

After the terrible events #lastnightinSweden , IKEA have sold out of this: pic.twitter.com/Bs1XI7ffKG — Jeanna Skinner (@JeannaLStars) February 19, 2017

And, inevitably, Stockholm syndrome raised its frightening head.

The more Swedes hear about Trump the more they dislike him. It's like reverse Stockholm syndrome. #lastnightinsweden — Paul Lander (@paul_lander) February 19, 2017

America, if you start to identify with your captor-President, please call. We can help. #LastNightInSweden #StockholmSyndrome — Last Night In Sweden (@LastNiteNSweden) February 19, 2017
