If you ever try to trick an entire nation into believing an actor is the current president of the United States, make sure both the actor and the president are right-handed, or else you may get called out on social media. 

A recent Instagram post suggests that just such a misstep happened when President Joe Biden’s “body double” was photographed signing something with his left hand. 

“Oops, Biden’s body double is left-handed,” the post says. “Casting director slipped up.”

In the photo are two images of Biden signing something. In the first image, he appears to be signing with his right hand. In the second, he appears to be signing with his left hand.
