Friends: Season Five Easter Egg - Gunther Continues

I was actually suprised to not find this egg on the list considering the fact that the back cover of the DVD lists Easter Eggs as one of the special features.

1. Go to the Special Features Menu on disc four
2. Select "Gunther Spills the Beans"
3. Press the right arrow key on your remote control. Three coffee cups will appear and when selected, Gunther pops up on the screen congratulating you and then getting frustrated.
