I love the easter egg feature on DVDs. I think one of the best ever is Gollum accepting the MTV award for best CGI character on the LOTR TTT DVD.
"Looking for" supplements is not the same as "watching supplements".
Especially when some of the supplements are advertised quite openly on the packaging. There are times where a supplement is mentioned on the packaging and does not even appear on the disc (oops).
Screw that. Here's your new car, have fun looking for the headlights switch.
