I've always loved Gag Factor 10. Always thought of it as one of the most memorable entries in the series. So many great scenes here that have been burned into my brain for years. Promise, Lizzy Liques, the first Ashley Blue Gag Factor scene (my favorite of the 4), Sapphire Rae which is one of my favorite all time scenes (by the way she works in a whore house now instead of doing porn), the Drew Allen scene...

Gag Factor 10 is just awesome, maybe its because it was one of the first I ever saw. All I know is that its one that I often go back to.
