Movie: More than love (A lot Like Love)

So, uh, a little boy is sitting in front of the house in the yard and digs a hole, and a neighbor peeking over the fence and asks:
- What are you doing, johnny?
And boy is she sad this:
- The goldfish died. Here arranged her funeral.
And the neighbor asks:
- Why such a big hole for your goldfish?
And johnny says:
- Then she's in the belly of that stupid cat.
