Grammar Dominatrix rears her head

Did I just hear the sentence "I was weary of trying it at first" on a national network commercial?

Girl, did you become Southern for one sentence? What are you telling me--that if I drink Silk soymilk I will lose my ability to distinguish between English words?

I expect the wary/leery/weary freak-out from the average ignoramus on the street--not from the professionals who write/film/edit nationally-televised commercials. No one caught that? Christ.
