The Adventures of Jimmy Neutron: Boy Genius, Season 2

Sheen:
Hey, Jimmy, I've got something to ask you. How come whenever we're in outer space, we don't have to wear helmets?

Jimmy:
Good question, Sheen, and the answer is quite interesting. You see -

[He starts explaining, but Carl's singing drowns it out.]

Carl:
[singing over] Moon, moon, moon! Spoon, spoon, spoon! June, June, June! Spittoon, spittoon, spittoon!

Sheen:
Uh, really?

Jimmy:
Mm-hmm.

Sheen:
But how come we don't need oxygen tanks?

Jimmy:

Carl:
[singing over] ♪ Star, star, star! You're so far, far, far! Can't go by car, car, car! ♪

Sheen:
Fascinating. Thanks.

Jimmy:
Any other questions.

Sheen:
No, I kinda got a headache.
