Last night, I got served a little bit too much of that poison, baby

Last night, I did things I'm not proud of

And I got a little crazy

Last night, I met a guy on the dance floor and I let him call me baby.

[Chorus]

And I don't even know his last name

My momma would be so ashamed

It started off, "hey cutie where you from"

And then it turned into oh no, what have I done

And I don't even know his last name.

We left, the club, 'bout around three o'clock in the morning

His pinto, sitting there, in the parking lot, well it should have been a warning

I had no clue what I was getting into

So, I'll blame it on the cuervo

Oh where did my manners go?

[Chorus]

I don't even know his last name

Oh my momma would be so ashamed

It started off, "hey cutie where you from"

And then it turned into "oh no, what have I done"

And I don't even know his last name.

Here we go...

Today, I woke up, thinking about elvis somewhere in vegas

I'm not sure how I got here

Or how this ring on my left hand just appeared outta nowhere

I gotta go take the chips and the pinto and hit the road

They say what happens here, stays here, all of this will disappear.

There's just one little problem.

[Chorus]

I don't even know my last name

Oh my momma would be so ashamed

It started off, "hey cutie where you from"

And then it turned into "oh no, what have I done"

And I don't even know my last name.

What have I done

What have I done

What have I done.

Oh, what have I done

I don't even know my last name.

Well it turned into, oh no what have I done

And I don't even know my last name

Yea, yeah, yeah...

I don't even know my last name

It started off "hey cutie where you from"

And then it turned into, oh no what have I done

And I don't even know my last name

Oh, yeah...
