If you've eaten already, OK - here's the strangest story of the day.
Park Ji-sung: Duracell Bunny of Sir Alex Ferguson's third great Manchester United team; the jack-of-all-trades South Korean who would willingly run his blood to water for the cause.
Well, the former midfielder has volunteered the secret behind his stamina and, at a guess, FFT isn't sure it'll catch on.
“My father went to catch wild frogs. I was skinny and weak and my father heard their juice would give me size and strength," Park revealed.
“It tasted very, very bad but I had to drink it because I wanted to be a footballer and everyone said I needed to be bigger and stronger.
“They said it was good for my health to become stronger and I ate everything that would improve my health.”
We'll never know if Park Snr. was right, but things certainly turned out OK for Jr. – as four Premier League titles, two in the Eredivisie and a Champions League winners' medal neatly demonstrate.
