What is this joke about?

Question

For weeks my sister-in-law, Carol, tried to teach her two young sons punctuation. She knew she'd succeeded when a rather talkative friend of hers visited one day. That night as Carol was putting five-year-old Kevin to bed, he said, “Mom, your friend must not have learned punctuation.” “Why do you say that?” she asked. “Because,” Kevin replied, “she talked with no periods at all.”

Answer 1

stupid

Answer 2

Answer 3

yeah, it means that she just kept talking and talking. also, she could've been talking fast.

Answer 4

she never stopped talking

Answer 5

It's about her friend talking to fast.

Answer 6

Carol's friend never stopped talking. She just kept going on and on and on and on and on......

Answer 7

She is finally successful in teaching her sons about punctuation

Answer 8

It means she wouldn't shut up.

Answer 9

bono, it means she has diahhrea of the mouth (runs off at the mouth; won't/doesn't shut up).  Kevin's apparently a smart kid.

Answer 10

aww, how cute. the kid doesn't really get punctuation and that it's only written, and the friend must have talked very fast, or had lotttts to say

Answer 11

WoW! Cute little boy!!!! He did get it!!

Answer 12

It basically means that Carol's friend never stopped talking. A period means that the sentence is over, so when he says "she talked with no periods at all," he means that she just kept talking and talking.
