Weary from his new duties as a father, Mr. Baldwin hands his babies out to the class to help babysit for the week. But after being paired together, Oscar and Bea quickly realize temporary parenthood may tear them apart.

In the clip, Oscar's rather short-tempered brain advises him that the assignment might be another good way to impress Bea.
