Fat bird and Church are... having a surprise party for Carolina. And they invited the Director, GLaDOS, and Lilith. ... Yep. (As an aside, the Director and GLaDOS seem to be involved in a lot of things together in this meme. They are perfect for each other.)

Goodness, I don't even know, man. Shuu just wants to cut up Carolina and see how she works because she's such an amazing human specimen. Church does not want this to happen because he thinks Carolina's kind of hot and anyway, who does that for a surprise birthday? Or ever? GLaDOS wants to help Shuu, Lilith is only there because they paid her to be, and the Director has to get everyone to back the fuck off and stop harassing his almost-best agent. His angryface scares everyone into submission.
