The Bernie Mac Show (2001)

S5E7 For Whom the Belt Tolls

While Bernie is away, the kids push Aunt Wanda's patience to the limit. In an attempt to maintain order, Bernie entrusts Aunt Wanda with "Big Mama's Belt" as a disciplinary tool. To their surprise, the children find they are more terrified of Aunt Wanda wielding the belt than they ever were of Bernie Mac himself.
