"I Saw Three Ships" is a traditional Christmas carol and was sung by Shelly Marsh in the Season Three episode, "Mr. Hankey's Christmas Classics".
Background
Shelly Marsh attempts to sing the song while playing the piano as Kyle Broflovski and her brother, Stan Marsh, make funny faces behind her. The song ends with Shelly throwing the piano at the boys in anger.
Lyrics
I saw three ships come sailing in
On Christmas Day, on Christmas Day
I saw three ships come sailing in
On Christmas Day, in the morning.
And what was in those ships, all three?
On Christmas Day, on Christmas Day
And what was in those ships all three
On Christmas Day, in the morning?
The Virgin Mary and Christ were there
On Christmas Day, on Christmas Day
The Virgin Mary and Christ were there
On Christmas Day, in the morning.
Let us all rejoice, amain,
On Christmas Day, on Christmas Day
And let us all rejoice, amain,
On Christmas Day, in the morning.
Shelly is starting to get pissed
On Christmas Day, on Christmas Day
Shelly got up and killed the turds
On Christmas Day, in the MORNING!
