Maybe 5-10 years ago at Delaware they ran a 3yo filly stake. One of them (not a long shot) acted up, and the rider got off. As he started to get back on he had one foot on the gate on either side but hadn’t sat down yet, when the gates opened. He was left standing on it as his filly took off with the field.

But to me the best will always be the guy who took his horse through that gap between the outside rail and where they parked the gate in the stretch in Maryland, and almost won. Love the announcer on that one.
