South Park - Season 1 - Eps 8: Starvin' Marvin
The four boys are at Cartman's house watching the "Terrance & Philip Thanksgiving Special" on television. During a break from the show, a Sally Struthers commercial convinces the boys that the prospect of a free "Taiko" sport watch with a five-dollar donation is irresistible. Typical greedy American youth. So Stan dials in, using his mother's credit card number and makes their donation.
