[Ads-l] "grow ups"??

[Joel Berson]

Is the following a simple typo (placing the "s" after the wrong word), or an example of some known type of error?  ("I/you grow up", "he/she grow-ups" instead of "grows up"?)


"With help from a young girl and a widower, a woman finally grow ups and takes on the real world."

A FiOs TV guide description of a movie.
