Hee hee! This reminds me of a few choice lyrics in a song by Lustra.
Scotty doesn't know,
That Fionna and me,
Do it in my van every Sunday.
She tells him shes in church,
But she doesn't go,
Still shes on her knees, and...
Scotty doesn't know, oh.
Scotty doesn't know-oh.
So don't tell Scotty!
If you haven't heard it before, it's a catchy song that has some funny lyrics.
