Madness.

Former France and Sales Sharks forward Sébastien Chabal has always been a bit of a character to say the least.

The 41-year-old also had stints with Bourgoin, Racing 92 and Lyon in a hugely successful career, representing the French national team on 62 occasions.

And while he was feared on the pitch, standing at 6ft 3in and weighing nearly 18 stone – his antics off hit have always made us laugh, including famously driving a SMART car while at Sale.

These days he’s still heavily involved in the game, and made a rather unusual appearance at the Hong Kong 7s this morning – dressed as a caveman singing the Proclaimers. Yep. It has to be seen to be believed…
