This tale of a crazy road trip with friends was written by Katy Perry together with Desmond Child ("You Give Love A Bad Name," "Who Let The Dogs Out") and the Swedish songwriter and producer Andreas Carlsson ("I Want It That Way," "That's The Way It Is").

Desmond Child told us how the song came together for Perry: "At that point when I met her she was between record deals. Then she got one at Columbia Records and then she was dropped from there and she went to the next thing.

And that song managed to survive all of those changes. It came out as the fourth single of her first record at Capitol, and it went to #1 (on the Dance and Pop Songs charts). That was like five, six years after we had written it.

LYRICS
You gotta help me out
It's all a blur last night
We need a taxi 'cause you're hung-over and I'm broke
I lost my fake ID but you lost the motel key
Spare me your freakin' dirty looks
Now don't blame me
You want to cash out and get the hell out of town

[Chorus:]
Don't be a baby
Remember what you told me
Shut up and put your money where your mouth is
That's what you get for waking up in Vegas
Get up and shake the glitter off your clothes now
That's what you get for waking up in Vegas

Why are these lights so bright?
Oh, did we get hitched last night dressed up like Elvis?
Why am I wearing your class ring?
Don't call your mother
'cause now we're partners in crime

[Chorus]

You got me into this
Information overload, situation lost control
Send out an S.O.S.
And get some cash out
We're gonna tear up the town

Don't be a baby
Remember what you told me [x3]
Told me, told me...
Shut up and put your money where your mouth is
That's what you get for waking up in Vegas
Get up and shake the glitter off your clothes, now
That's what you get for waking up in Vegas
That's what you get, baby
Shake the glitter, shake, shake, shake the glitter, c'mon!
Give me some cash out, baby
Give me some cash out, baby
