Ellen will be very annoyed to hear what some half-brained twit did to her favorite "frozen concoction":

"Drink up," she said, mixing the drinks and refilling Cerveny's 16-ounce glass. "Come on, Kris, I'm drinking faster than you. . . . Have some more."

But Plambeck's margaritas weren't just mixed with tequila and lime. During that two-hour drinking session at 4511 S. 12th St. last August, she was pushing Prestone, disguised in the green liquid.

As always, the perpetrator is taking the tried-and-true redneck "if I'd meant to kill her, she'd be dead" defense.
