(Parts in Italic are lyrics to the song)
SpongeBob: I'm ready! I'm ready, I'm ready, I'm ready, I'm rea-(gasp). Closed?
(Fireflies chirp in background)
SpongeBob: NO!!!! (echoes in background).
Please, get back to work, I don't like downtime. (SpongeBob wakes up and grunts).
Gary, what day is it?
SpongeBob: Monday? Oh-ho, Monday!
Thank gosh it's Monday, my number one day!
Back in the saddle at work I can shine. I love the rat race and the starting line
Is Monday, thank gosh it's Monday!
Sing with me, Gary! (Gary meows as SpongeBob gets ready for work)
It's Monday, it's Monday, it's Monday,
Thank gosh it's MONDAAAYYY!!
Squidward: Will you pipe down?! Can't you just frown and grunt like the rest of us? You're the only moron in the whole world who actually likes Monday!
SpongeBob: Oh, porpoise pants, Squidward. Plenty of people love Monday, just as much as me.
Squidward: Like who?
Patrick: Thank gosh it's Monday! Squidward: Oh, no. Patrick: The yummy-yum-yum day! Squidward: Please stop. Patrick: I'll have a Krabby Patty! SpongeBob: Or two, Or three! Patrick: Yeah, come on tummy, sing with me! It's Monday, thank gosh it's Monday!
Bikini Bottomites: Thank gosh it's Monday! Thank gosh it's Monday! M-O-N-D-A-Y! M-O-N-D-A-Y! It's Monday! Thank gosh it's Monday!
(Bikini Bottomites continue to chant M-O-N-D-A-Y and continues to get louder as Plankton talks)
Plankton: Ugh! Karen, my computer wife? Do you know why no one eats here at The Chum Bucket?
Karen: 'Cause the food's really bad?
Plankton: Yes, but when I steal the secret formula for the Krabby Patty, the lines around the block will be MINE!!! and not that that greedy Mr. Krabs.
SpongeBob: Thank Gosh It's Monday! My number One day!
Mr. Krabs: Thank gosh it's Monday! Now get to work!
(SpongeBob makes scattering noises while sharpening his spatula)
SpongeBob and Bikini Bottomites: It's Monday! Thank gosh it's Mon-DAAAAAAAAYYYYYY!!!!
Mr. Krabs: Oh, yes it's Money DAAAAAAAAAAAAAAAAAAAAAAAAAYYYYYYYYYY!!!!!
(Mr. Krabs then throws his money in the air while he sings, and franticly picks them up afterwards)
