Sonny Wool's a black sheep in the playoffs

It looks like Sonny Wool the psychic sheep may be on his way to bleating the odds.

The four-legged foreseer made his pick at Berhampore School, choosing the All Blacks to beat Argentina in this Sunday's quarter-final showdown in Auckland.

Sonny Wool checked out the Argentina container of food before committing to New Zealand. He made believers out of the children watching, who went wild, chanting "All Blacks" repeatedly following his pick.

His agent said it would be a bit touch-and-go who he'd pick, at first.

"He had a good wee sniff around the Argentina flag, but then he decided better off and apparently we can do it without Dan Carter," Dan Boyd said.

"Sonny Wool is backing Colin Slade all the way."

Sonny's owner Beverley Dowling insisted they were doing everything to make sure his sheepish predictions were fair.

"We don't do any training through the week and we swapped the food over to the left-hand side because we had a few people saying we're being baa-ad, so we changed it over to prove things."

This is the sheep-seer's fifth pick, after correctly predicting all four All Blacks games at the tournament so far.
