U.S. - Well, this is embarrassing. As Joe Biden was answering a question during CNN's 742-hour town hall on climate change last night, his head fell off, casting doubt on his ability to lead the country effectively at his age.

The presidential candidate began responding to the question, saying, "Yeah, I think climate, uh, stuff is very important for us here in Canada, uh, a vital issue facing us here at the turn of the 19th century. In fact---whoopsy-daisy!" As his head was bobbling, well, like a bobblehead, it suddenly lunged forward and came clean off, toppling to the floor. He continued to answer the question, though he still didn't seem to be certain where he was.

Malfunctions like this have plagued Biden's campaign, from the time his eye peeled off revealing a horrifying lizard eye to the time both his arms started doing the Macarena uncontrollably. The constant physical errors are starting to cause some supporters to wonder if he'll be able to hold up at all should he take the White House.

"I'm just not sure that a guy who can't go a few minutes without his head coming clean off is in a good enough mental and physical state to run the country," said one man CNN interviewed after the debate. "It seems like the guy in the White House should be able to retain basic information, know where he is most of the time, and not have his head tumble off his shoulders while he's talking."

Biden's aides assured everyone that he is in "peak physical condition," blaming the malfunction on defective staples in Biden's neck.

Beto O'Rourke took the opportunity to lament how terrible the world is, saying, "We got no food, we got no jobs, Joe Biden's HEAD IS FALLING OFF!"
