Whenever I find a horseshoe crab with its tail cut off (usually by a boat propeller), I use a sheep castrator and bands to attach a dowel as a prosthetic. It can now flip itself over when it gets turned upside-down.
David Marcus gives more examples and shows us how to de-gaslight people like Trump. That said, I'm one of the people who hope Trump wins the nomination (especially if it turns into a convention mess). I think Clinton will crush him in the general and that it will do enough damage down-ticket and to the GOP in general that it's worth the risk.
