You Want My Sister

I took you home to meet my family
You asked if you could stay the night
Honestly I would not have minded, no
Till you gave my sister the eye

We sat for dinner round the table
Big mumma's famous shepherd's pie (big mumma)
I dropped my fork so went to find it, oh
Saw your hand on my sister's thigh

Oh I
Don't know why
I thought I was your mister
But you just want my sister
Oh, why have you done this to me, baby?
Now I know why you kissed her
When we played family twister
Oh, how awkward Christmas will be for me

And now you're standing at the altar
You look so beautiful in white
But it's not me who's standing with ya, no
It's that backstabbing bitch sister of mine

Oh I
Don't know why
I thought I was your mister
But you just want my sister
Oh, why have you done this to me, baby?
Now I know why you kissed her
When we played family twister
Oh, how awkward Christmas will be for me
