The one that comes to mind is when they said Joe Rogan was taking horse de-wormer for covid. Which isn't true. The drug in question, Ivermectim, has a lot of variations used for different things, once of which, is horse dewormer, but the kind Rogan was taking was the kind you get from a pharmacy, which has been common practice for many years, until people started using it to fight covid (apparently it works) and the media started attacking it and painting it as horse dewormer.
