According to some spam

"Brittney Spears has a 4 hour sex tape!"

Ugh.  Even if she wasn't really kinda yesterday's news, and I really had an interest in her, why would I want to watch her doing that for four hours?  I mean, you'd get hungry or have to make a head call before the movie was up...  Lawrence of Arabia gave you and intermission, at the 2 hour mark, WITH Overture...

Four hours is not a selling point for a sex tape featuring one pair of players.
