There is a girl in Las Vegas who offers an 80 minute hot stone massage for $160.  She brings a crock pot with the stones hot in them, and keeps half of them warming while using the other half and swapping them out.  She has a mix CD that is perfectly time for when she does each part of the back, when the flip comes, and so forth.  With the promise of a tip, you can touch her as she touches you.  It is really cool to get a REAL massage for that long.  Down-right decadent.

As the 80th minute approaches, she mentions that the tape actually goes to 90 minutes and for another $20 she can keep going if you like...  

Wow, is that last ten-minute tug job an incredible stress reliever.
