"BMO's Pregnant Song" is a song sung by BMO in the episode "James Baxter the Horse." It sings the song with an egg in a red cup taped to its body, which it apparently considers "being pregnant." After the song, a passing butterfly knocks the egg out of BMO's hands and breaks it.
| Oh, oh, BMO, how'd you get so pregnant?|
Who's the mother?
Oh, who's the father?
Shh, I'll tell you if you keep it a secret.
| We will, we will, we will!|
All right, last night, an electric presence came into my room and said,
"BMO, I need your perfect body to host the human incarnation of a baby!"
- This song was censored in Australia and many other countries as it includes sexual references.
- The song could possibly be referencing how the Virgin Mary was impregnated.
