Harry to James, Albus, and Lily:

Harry: Call it love and devotion

James: Wrong person Dad!

Lily: Check who you're texting before you send the message!

Harry: Call it the mom's adoration (foundation)

Lily: Seriously, wrong person.

Harry: A special bond of creation, hah. For all the single mums out there going through frustration.

Lily: Ummmm...

Harry: James Potter, Lily-Da-Potter, Albus-Severus, sing, make them hear

Albus: So you used James's and Lily's last names but not mine? Wow.

Harry: She works the night, by the water.

Albus: Who is this girl that you're staking?

Harry: She's gonna stress, so far away from her father's daughter

Lily: Ummm who is this?

Harry: She just wants a life for her baby

Albus: Obviously, or else she'd be a murderer. A normal mother doesn't kill her babies in a rampage.

Harry: All on her own, no one will come, she's got to save him (daily struggle).

Lily: Who is this girl?

James: Is she attractive?

Lily: Oh lord. James, Dad might be cheating on Mom.

Albus: He's not smart enough to get another girlfriend.

Harry: She tells him "ooh love". No one's ever gonna hurt you, love, I'm gonna give you all of my love, nobody matters like you (stay up there, stay up there). She tells him "your life ain't gonna be nothing like my life (straight).  You're gonna grow and have a good life, I'm gonna do what I've got to do" (stay up there, stay up there).

Albus: You stalker!

James: Is she attractive?

Lily: *facewall*

Harry: So, rockabye baby, rockabye, I'm gonna rock you

James: I'm not a baby I'm 16! Albus is 15! Lily is 13!

Harry: Rockabye baby, don't you cry, somebody's got you.

Albus: What baby did you kidnap?

Harry: Rockabye baby, rockabye, I'm gonna rock you. Rockabye baby, don't you cry. Rockabye, no (Rockabye-rocka-rocka-rocka-bye) (oh). Rockabye, yeah, yeah (Rockabye-rocka-rocka-rocka-bye)

Lily: I'm slowly starting to believe Albus.

Albus: You're giving me the creeps.

Harry: Single mom what you doing out there?

Albus: We are not single mothers. Well, Lily might me.

Lily: AM NOT!

Harry: Facing the hard life without no fear. Just see and know that you really care cause any obstacle come you well prepared, and no mamma you never shed tear cause you haffi set things year after year and you give the youth love beyond compare. You find the school fee and the bus fare

Albus, James, and Lily: WRONG PERSON DAD!

Harry: Hmmmm more when paps disappear in a wrong bar can't find him nowhere. Steadily you work flow, heavily you know so you nah stop. No time no time fi a jeer

Albus: Fi a jeer? Is that a word? Those aren't words.

James: Wtf? U Sirius?

James: *serious

Harry: Now she gotta a six year old, trying to keep him warm, trying to keep all the cold.

James: Who has a 6 year old?

Harry: When he looks her in the eyes, he don't know he's safe when she says "Ooh love" No one's ever gonna hurt you, love, I'm gonna give you all of my love, nobody matters like you. So, rockabye baby, rockabye, I'm gonna rock you
Rockabye baby, don't you cry. Somebody's got you Rockabye baby, rockabye, I'm gonna rock you. Rockabye baby, don't you cry (Bidda-bang-bang-bang, alright then) Rockabye, no (Rockabye-rocka-rocka-rocka-bye) (Oh) Rockabye, yeah (Rockabye-rocka-rocka-rockabye) (yeah)

Albus: Which baby did you kidnap?

Lily: I'm a bit concerned about your mental health.

Albus: Same.

Lily: Dad, maybe you are a baby.

Albus: He is.

Harry: Rockabye don't bother cry. Lift up your head, lift it up to the sky, yo. Rockabye don't bother cry. Angels around you, just joy your eye.

Albus: Don't bother? Who's Rockabye?

Lily: Rockabye is a lullaby.

Albus: Dad sang us, "CHAIRABYE BABY!" Instead of Rockabye.

Lily: Oh yes!

James: Oml.

Harry: Now she gotta a six year old, trying to keep him warm, trying to keep all the cold.

James: What 6 year old?

Harry: When he looks her in the eyes, he don't know he's safe when she says. She tells him "ooh love" No one's ever gonna hurt you, love, I'm gonna give you all of my love, nobody matters like you (stay up there, stay up there). She tells him "your life ain't gonna be nothing like my life (straight). You're gonna grow and have a good life, I'm gonna do what I've got to do" (yeah) So, rockabye baby, rockabye (Rockabye-rocka-rocka-rocka-bye) I'm gonna rock you.

Albus: This sounds familiar.

Albus: Never say that again. Nice lyric prank tho. But Rockabye? Seriously?

James: It's a song?

Lily: OOH! I'm so stupid!

Harry: You're not.

Albus: Dad and James are.

Harry and James: HEY!

Albus and Lily: It's true though.
