"Ajax Driving School, helping Asians learn to drive for over 20 years!" Skinny ethnic-Chinese looking man with big black-rimmed glasses and buck teeth on screen: "Fank you Awax dribing skoo!", bows and smiles at camera. Peels out in little mini-car, bouncing off two cars on his way down the street.
"Uncle Tom's fried chicken and watermelon, we're your source for eats this Juneteenth!" Big fat black man and woman grin at the camera, chicken in one hand and watermelon in the other, with 8 kids sitting around a picnic table in the backgroud: "MMM MMM! That sho' is some fine ass chicken, Unka Tom!" Kids suddenly start fist fighting over buckets of chicken on a picnic table behind the obese couple. Cries of "I gets da leg, I gets da breast" can be heard. "Remember Uncle Tom's when you celebrate YOUR Juneteenth!" "Remember, you're not a slave anymore - choose Uncle Tom's!"
White woman walking alone into a dark parking garage, or huge empty out door parking lot. Suddenly two menacing black youth approach from the shadows. "Yo bitch, give up the purse." One flashes a knife, the other a toothy grin with sparkling gold teeth. The white woman says, "Please don't hurt me... I have my money right here.." Reaches in to her purse, pulls out a small pistol and shoots both of her assailants. Voice over: "Jack's Guns, helping protect innocent Americans for over 70 years." The woman has the gun pointed at the men writhing on the floor, now on her cell phone, "Yes, police?", voice fades as commercial ends.
I can think of plenty more, but you get the idea. Never see these on television!
