Simpsons season 4 easter eggs?

[Guest hockeytown9321]

Does anybody know of any eggs on the season 4 set?

Insert the third disc of the DVD set and during the episode 'Marge Vs. The Monorail' press the 'Audio' button on your remote control to switch to the fifth audio track. There, you will notice that this episode features a new commentary track by Matt Groening, Al Jean, Mike Reiss, David Silverman and Conan O'Brien that is not otherwise accessible

I think there's two Audio commentaries for Marge vs. The Monorail, other than that I don't know of any. I'm not even sure if the second commentary is an Easter Egg, but it's a 50/50 chance.

 

Edit: Got beat. If you use a PS2, just click the right analog stick of the PS2 Control until it says Audio 5.
