The Big Steal is the first Simpsons KFC commercial.
Plot[]
Homer orders a 15-piece bucket of chicken and a two liter bottle of 7-Up at KFC. Not realizing that the 7-Up is free, he says that the cashier didn't charge him for the drink, but just as he's about to walk out with his purchases, Homer sees Eddie and Lou outside, much to his shock, and is afraid that he stole it.
Before the cashier can tell him about the deal, Homer runs into the men's restroom with his purchases so that he won't get arrested, and jumps through an open hole, but can't get through it (due to his weight).
He then sees Abraham Simpson II walk by, and tells him that he needs his help because Eddie and Lou are after him due to swiping the 7-Up without purchasing it. However, Abe tells Homer that KFC is giving the 7-Up away for free, so he grabs both the 7-Up and the bucket from Homer, and laughs as he walks away.
Homer then gets pushed out of the hole by the cashier, and thuds to the ground off-screen.
After the commercial shows the info about the free 7-Up deal, Homer is seen lying on the ground in pain from getting pushed out, and the cashier says to him that he forgot his moist towelettes for his food. Homer then lies his head on the ground and moans.
