Ahhhhhh! Nope, can't think of any!
Show me a pilot who's never fcuked up and I'll show you a liar, and someone I'll never fly with.
After a rushed pre-flight of my trusty Huey I got airborne, and was surprised to find something red flapping around the top part of the windscreen. Rushed preflight = pitot cover left on! Fortunately monitoring IAS is not as critical in a helicopter as compared to a fixed wing aircraft when on final to land, so the only thing hurt was my pride.
