OK, what?

There is not a whole lot that can leave the usually unflappable At The Races presenter Matt Chapman speechless. But after this he was nothing short of dumbstruck, tongue-tied, voiceless. The man was, quite literally, without speech. He was flapped. All it took was a brief but beautifully bizarre exchange between jockey Josephine Gordon and the on-course presenter Derek Thompson.

One of our favourite clips in a long time! Kudos to @MCYeeehaaa, @tommoracing and @josephinegordo. https://t.co/WvkVM5KBey

Here's how it played out. Derek: And was your mum watching from Devon tonight, as always? Josephine: She'd be in bed. Derek: If I know your mum, she certainly won't. "If I know your mum, she certainly won't."

"If I know your mum, she certainly won't."

"If I know your mum, she certainly won't."
