Video: One of Canada's rugby players gets a nasty surprise from her team-mate in the tunnel
She did NOT see this coming.
This is definitely one way to relieve the tension before a World Cup Final, as Jessica Dovanne turns around to smack Andrea Burk in the tunnel on their way out on to the pitch.
We're now imagining the carnage if Simon Zebo tried something similar with Paul O'Connell...
He'd have to leave the country.
The incident takes place at around the 12-second mark, and thanks to Keith Kelly for sending it our way.
