Daddy Pig forgets Mummy Pig's birthday, and fears he will be in big trouble with her.
Narrator: It's a special day today, as Mummy Pig is celebrating her birthday.
Peppa: Happy birthday, Mummy!
Mummy Pig: Why, thank you, Peppa! How lovely! By the way, where's Daddy Pig?
(Inside Mummy and Daddy Pig's bedroom, Daddy is hiding under the covers)
Daddy Pig: Oh, dear...oooooh!
Narrator: Daddy doesn't sound very happy. I wonder what's wrong?
(Peppa comes in)
Peppa: What's wrong, Daddy?
Daddy Pig: Oh, Peppa! It's a disaster! I've...forgotten Mummy's birthday!
Peppa: You forgot WHAT?!?!
Daddy Pig: Exactly! I didn't know it was her birthday until I heard you downstairs! And if Mummy finds out, I'll be in huge trouble!
Peppa: Don't worry! I won't tell her! Let's keep it a secret!
Daddy Pig: That's a relief!
(Peppa and Daddy come downstairs)
Mummy Pig: What took you so long, Daddy Pig?
Daddy Pig: Err...I was...er...thinking of a birthday surprise!
Mummy Pig: That's nice! But what's the matter? Got butterflies in your tummy? You sound quite nervous.
Daddy Pig: N-not at all!
Mummy Pig: Have you forgotten my birthday?
Daddy Pig: No! Why would I?
Mummy Pig: You're lying, Daddy Pig!
Daddy Pig: W-w-what do you mean?!
Mummy Pig: I bet you forgot my birthday then tried to cover up the fact!
Daddy Pig: OK, you win. I forgot your birthday. I'm sorry.
Mummy Pig: Well, this won't work now. Good job. Hope you're happy, loser!
(Mummy Pig walks out)
Narrator: Oh, dear. Mummy Pig doesn't want to talk to Daddy Pig anymore.
Daddy Pig: Wait! I didn't mean to...OOOOOH!!!
(Daddy Pig begins to sob)
