Last name

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.
Oh, my momma would be so ashamed.
Well, it started out, "Hey cutie, where you're from?"
And it turned into, "Oh no, what have I done?"
And I don't even know his last name.

Today I woke up thinking 'bout Elvis somewhere in Vegas.
I'm not sure how I got here, or how this ring on my left hand, just appeared out of nowhere.
I gotta go, I grab the chips and my Pinto so I 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.
Yeah, yeah, yeah, yeah, yeah
I don't even know my last name.
