Here's from a Purdue Online Writing Lab article on comma usage, "Extended Rules for Using Commas":
1) Do you feel a comma is really incorrect in the first sentence?
2) I agree that no comma is needed in the second sentence. But what if it were longer, for example,
I turned the corner of Fifth Avenue in a state of frenzy I have not experienced since, and ran smack into a patrol car.
would you say it is still incorrect to put a comma between the verbs?
13. Don't put a comma between the two verbs or verb phrases in a compound predicate.
INCORRECT: We laid out our music and snacks, and began to study.
INCORRECT: I turned the corner, and ran smack into a patrol car.
