Hangover Part IV

I'm not entirely sure what the plot of The Hangover Part III is, but rumor has it that Britney Spears makes a cameo. That perfectly coincides with the reported Vegas deal she's negotiating. In fact, my proposal to the producers of The Hangover is to spin Britney off and do a fourth Hangover staring her.
It may sound like a crazy idea on paper because of Britney's newer, cleaner image. But, imagine all the hijinks she could get up to. For instance:
- Britney gets lost looking for a Starbucks at 1 a.m.
- Britney can't quite figure out how the craps table works
- One of Britney's children pulls a slot machine lever and wins $1M
- Britney has a chase scene on the casino floor with paparazzi
- Britney finds a dog shelter and tries to adopt every dog
- Britney steals a cop car (kidding, that's already been done)
Either way, those ideas are way better than a Vegas casino blowing $100-$120M on Britney for two years.
You have to understand Britney's fan base. Do they have the money to afford to see Britney in Vegas? Imagine a ticket, flight and hotel, then add on food,drinks and gambling (if of legal age) and you're talking in excess of $500. Britney's fans love her, but how many have that kind of money to blow?
A Vegas set-up works for older artists like Celine Dion and Elton John because their fans are older and have disposable income. Not so much for 17-year olds or 20-year olds or even 24-year olds.
Obviously, the money is tremendous for Britney. Who would turn down $100M? However, I think most people would agree that Britney would probably get bored quickly. I can't imagine her putting on the same show in the same place for two years.
Personally, I'd rather watch The Hangover Part IV staring Britney Spears. Who's with me?
