The prize on the line Sunday night at 8: Half a million dollars.

Last night, Jaskinski's chummy shenanigans paid off when Ryan Quicksall, an Ohio college student, rewarded Adam's loyalty act by booting Sheila Kennedy, the weepy, 46-year-old single mom from California.

Jasinski "proved" his allegiance by letting Quicksall win a boogie-board water-torture challenge.

Jasinki, though, had also been pretending to be Sheila's best bud - so much so that after her elimination she said she and Adam would always be friends.

Wait till she compares notes with the other exiled ex-housemates and learns about the lying and the scheming.

The last seven evictees - the show locks 16 strangers together in a Los Angeles house for up to three months - get to vote to decide who wins the big money.

Jasinski, a Camden County Community College alum who now lives in Florida, certainly thinks his affable ways will pay off, since last night he told Ryan he felt confident he'd get the $500,000.

Even Quicksall rated his own chances of winning a lowly 3 out of 10, in a conversation with host Julie Chen.

Jasinski's behavior as a contestant, however, hasn't exactly endeared him to the world.

He works in public relations, and had done work for the United Autism Foundation - until February, when he called autistic children "retards" on the show. The foundation fired him "since he caused tremendous damage."

Lowe's, the home improvement chain, dropped out as a sponsor because of the remark.

Then Jasinski called a housemate a gay slur, prompting CBS to say Jasinski's offensive language would not be part of any future broadcasts.
