On Sunday, May 13, Cartoon Network will present JOHNNY BRAVO'S MOTHER'S DAY MAMA-THON, a 7-hour tribute to the “Lady Who Brought Us the Sultan of Self Regard, His Mama.” During the “Mama-Thon,” which runs from 12-7 pm (ET/PT), viewers can witness the many facets of Mama's personality, including disciplinarian (she wields a paddle in PREP SCHOOL JOHNNY), protector (leading a team of commandos to the mall to rescue her beloved son in LAW AND DISORDER), and even diva (Mama does a Marilyn Monroe impression in DUDE RANCH DOOFUS).
