Ian Terry, the brainy young Tulane student who streaked, crawled under tables, and wore a dog costume when he came time to cristen his alliance with a sound effect (quack) won the $500,000 top prize of “Big Brother” Tuesday, bringing an end to the season and to the scorched earth reign of Dan Gheesling , the football coach and former winner, who admitted to the jury that he had to stab every one of them in the back to get where he landed.

They didn’t take it well.

All but Danielle Murphree, the gullible pupil of Danielle, who was lied to and blindsided three times before she agreed to throw the final head of household competition because Dan asked her to. Even when she ended up ousted from the final three and became the final jury member, and learned from Ian that he too had a final two agreement with Dan (to which he had sworn on his grandfather’s cross), she made one of her shocked faces and still voted for Dan. In fact she was the only one in the 6-1 vote to go for the ruthless Dan.

“This is easily the best day of my life,” Ian said after the win.

Finishing second got Dan a consolation $50,000 but it was Frank Eudy, a victim of one of Dan’s most spectacular blindsides, who got the $25,000 fan favorite award.
