Vegetables are bad enough. They get worse if you don't eat them
I've found some in the fridge, made me sick to even see 'em
They were hiding in the back, beyond identifying
Last night I saw something worse. There's no denying
My sister kissed her boyfriend, my sister kissed her boyfriend
My sister kissed her boyfriend
My sister kissed her boyfriend (kiss kiss kiss)
My sister kissed her boyfriend (smooch)
It was totally disgusting, disgusting to the end
My sister kissed her boyfriend
La la la la la la la
La la la la la la
La la la la la la la

Sometimes we catch our dog digging in the garbage can
Why he'd want to eat that I'll never understand
I thought it was the grossest thing I'd ever have to see
But what I saw last night you won't believe
My sister kissed her boyfriend, my sister kissed her boyfriend
My sister kissed her boyfriend
My sister kissed her boyfriend (kiss kiss kiss)
My sister kissed her boyfriend (smooch)
It was totally disgusting, disgusting to the end
My sister kissed her boyfriend
La la la la la la la
La la la la la la
La la la la la la la

One time I cut my finger and I didn't even cry
But when I tried to look at it, I had to close my eyes
It was bleeding and so icky, it cut me to the quick
But what I saw last night made me sick
My sister kissed her boyfriend, my sister kissed her boyfriend
My sister kissed her boyfriend
My sister kissed her boyfriend (kiss kiss kiss)
My sister kissed her boyfriend (smooch)
It was totally disgusting, disgusting to the end
My sister kissed her boyfriend
It was totally disgusting, disgusting to the end
My sister kissed her boyfriend
