Not My Mama's Grammar

I enjoy watching the Food Network, the Cooking Channel, and Bravo "Top Chef." One of my favorite show is "Not My Mama's Meals."There is a recently aired commercial in which the announcer says "There’s isn’t a challenge he isn’t up for…."

The mere fact that my word check/grammar check pops up two squiggles in one sentence tells me that the script should have be edited. That sentence contains a double-negative and ends with a preposition.

Bobby Dean is up for every food challenge. He is up to the challenge to reduce the fat and calories in his mother's recipes. I am up for the challenge to find more gaffs in the spoken word.
