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

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 3 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?

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

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
