Chook Me!

What episode of Robot Chicken is this?

There is an episode of Robot Chicken where two scientists are standing at a chalk board. One of them marks something and they both start laughing, Can anyone tell me which episode this is on? I have to know because this is one of the funniest scenes from the show. Thanks.
