I don't know if this is from a movie or a tv episode, but I'm fairy sure it's from the 80s or 90s.
Two men are standing on a bridge overlooking a pond on the older man’s property. They throw what looks like white bags into the pond, and there is an alligator in it. The older man talks and he said something about the alligator having bitten his leg?
