I like Easter Eggs and mistakes and that. I heard there was one where you use the cards on Eva, then quickly turn around and do it while turning. Then Manny will say what Eva just said! Ain't got it to work yet though. And everyone knows of when Manny has a balloon and he makes a noise while walking down the corridor.
Oh, and one more thing. Take this Sprouter. You might need it nowadays. The GF Network forum ain't the quaint little place she used to be...
