Jackie: Hi, my big brother. My name is Jackie. I was born about a month ago, Macusoper.
Macusoper: You're rather cute, Jackie.
(Macusoper's Dad & Warren Cook appear)
Macusoper's Dad: (400% loud voice, happy) Welcome to the family, little guy!
Warren Cook: Hi, Jackie. My name is Warren Cook.
Curiousgorge55: Macusoper, your sister is cute. My name's Curiousgorge55, little guy.
Jackie: Thank you for all your comments.
Curiousgorge55: You're welcome.
- It is revealed that Macusoper's sister was born about a month ago.
- This is the second Macusoper gets grounded video by Curiousgorge55 to have a female appear.
- Although this is not a grounded video.
- When Macusoper's Dad says, "Welcome to the family, little guy," it is a reference to "The New Mcall Baby", where George W. Bush says the same thing.
- If Curiousgorge55 never included Macusoper's Mom in any of his videos, Jackie might've been born while Macusoper's Mom was on vacation.
- Jackie might've taken a plane home.
- This breaks the record of "Most voices in a Curiousgorge55 video", with 5 voices instead of 4.
- In this video, Macusoper says that Jackie's cute. This may be because he didn't want more trouble, although it is proven by his surprized face that he thinks Jackie is cute.
- Although Macusoper dislikes Jackie in other grounded series, Macusoper likes his sister in the series.
- Jackie is troubleless, giving Curiousgorge55 no reason to make a grounded series out of Jackie.
