A older man and two boys (both wearing orange) are sitting, with feet dangling, over an alligator infested reservoir.
The man and his sons are throwing pies at the mother.
In sentence 1 people are sitting but in sentence two they are throwing pies. It is unlikely that a person could be sitting while also throwing pies at their mother
