Easter eggs on Simpsons Season 8 and Superman Ultimate Collection...?
 

Hope it's okay to post this here... :)

Simpsons: Season 8
I've seen the deleted scenes eggs on each disk, but I read somewhere there was a different menu with an extra commentary somewhere, but can not find it. Is this true? Are there any bonus/hidden commentaries or other eggs besides the deleted scenes accessed from the button on the projector?

Superman: The Ultimate Collection
Any easter eggs on this?

Thanks for the help!
