In an interview with CNN, Biden explained how he was injured (initially believed to be a bone fracture) from just playing with his German Shepherd Major after showering. While he said "it is not a very exciting story", users on social media definitely had a different opinion, commenting on the odd behaviour of the 78-year-old politician.
The story baffled a lot of Twitterians, as they tried to imagine how exactly the incident happened and some did not miss the chance to mock the politician, producing some weird memes about the whole situation.
