MH&MH: A very merry unbirthday, to us, to us!
(unknown lyrics)
MAD: Oh, a very merry unbirthday;
MARCH: A very merry unbirthday;
MH&MH: A very merry unbirthday to us!
(instrumental by the teapots)
MARCH: A… very merry unbirthday–to me
MAD: To who?
MARCH: To me.
MAD: Oh, you!
MARCH: A very merry unbirthday–to you
MAD: Who, me?
MARCH: Yes, you!
MAD: Oh, me!
MARCH: Let’s all congratulate us with another cup of tea.
A very merry un-a-birthday to ohhhhhh yooou!
MH&MH (spoken): No room, no room, no room, no room, no room, NO ROOM!
Alice (spoken): But I thought there was plenty of room…
MARCH (spoken): Ah, but it’s very rude to sit down without being invited.
MAD (spoken): I’ll say it’s rude! It’s very, very rude indeed! (lightly chuckles)
DORMOUSE (spoken): Very, very, very rude indeed! (snores)
Alice (spoken): Well, I’m very sorry… but I did enjoy your singing, and I wondered if you could tell me…
MARCH (spoken): You enjoyed OUR singing?
MAD: (spoken): Oh! What a delightful child! And uh…(inaudible)…get so excited… we never get compliments! You must have a cup of tea!
MARCH (spoken): Ah, yes, indeed… the tea… you must have a cup of tea!
Alice (spoken): That would be very nice. I’m sorry I interrupted your birthday party… uh, thank you.

MAD (spoken): Of course not! (chuckles) This is an unbirthday party.

MARCH (spoken): It’s very simple. Now–30 days have Sept-no… well… an unbirthday–if you have a birthday, then you…(laughs) She doesn’t know what an unbirthday is!
MAD (spoken): How silly! Ho ho ho! Well… I-I… ahem… I shall (“illucidate?!”)…
