Painful in more ways than one.
No one likes to fall off their bike and have it seen by over 4 million people.
Unfortunately, it was Kendall Jenner's turn to taste that kind of infamy on social media, after Khloe Kardashian posted a video on her Instagram account of Kendall trying to stop her bike but face-planting instead.
Of course, this drew the wrath of social media users, who were quick with some hilarious responses.
Some people also came up with some new commercial ideas for Ms. Jenner.
Sure, it happens to everyone, but that doesn't make it any less funny.
