That's What You Get for Stating a False Cause

Katy Perry, another one of my favorite female artist. Though I love her and her music deeply, it doesn't mean that I cannot recognize a fallacy in her songs when I see one. In her song Waking Up in Vegas, Katy uses the phrase "that's what you get for waking up in Vegas" trying to say all of the bad luck that occurs in the song and is seen in the music video attached is because you went to Vegas. This isn't the cause. They were irresponsible and didn't know when to cash out when they had the chance. They instead used that money to party more. Instead, she should say "that's what you get for PARTYING in Vegas." However, it does not match the rhyme scheme as well and I don't feel the song would have done as well. Below are the lyrics in case you don't know the song.

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 roll the cash out
And get the hell out of town
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
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
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
Remember what you told me
Remember what you told me
Told me, you told me, 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
That's what you get baby, shake the glitter, shake, shake, shake the glitter
Give me some cash out, baby
Give me some cash out, baby
