On Saturday, Chelsea Clinton sent out the single stupidest tweet of all time.

Clinton, after she saw the cover of a Lincoln Day Dinner program showing a photo of Abraham Lincoln wearing a “Make America Great Again” hat, took to Twitter to question whether or not Abe ever wore a Trump hat or not.

Please tell me this is photoshopped. Please? https://t.co/WezDQx6IvT

Here is the original tweet that prompted Clinton’s reply:

Twitter users were brutal to Chelsea, seizing the opportunity to mock her for the ill-informed tweet:

Nope Lincoln was wearing that exact hat at the Theater

It's as real as those Bosnian snipers.

Whether she was joking or just being sarcastic, Chelsea’s tweet gave many the opportunity to mock her.

She also gave many of us a great laugh as we pondered whether or not Abraham Lincoln ever did actually wear that red hat.
