Everyone at the powerplant thinks Homer is crazy when he shows up in a pink shirt and want to give him a mental health exam. He has Bart take it for him and ends up in a looney bin with Michael Jackson.
Lisa, it's your birthday. God bless you this day. You gave me the gift of a little sister, and I'm proud of you today. Lisa, it's your birthday. Happy birthday, Lisa. Lisa, it's your birthday. Happy birthday, Lisa. I wish you love and good will. I wish you peace and joy. I wish you better than your heart desires. And your first kiss from a boy. Lisa, it's your birthday. Happy birthday, Lisa. Lisa, it's your birthday. Happy birthday, Lisa.
(Mr. Burns and Smithers review the security camera footage at the power plant.) Mr. Burns: Wait a minute. Go back. (Tape rewinds) Mr. Burns: Zoom in. (Screen zooms in to Homer.) Mr. Burns: Why is that man in pink? Smithers: That's Homer Simpson, sir. He's one of your boobs from Sector 7-G. Mr. Burns: Simpson, eh? Well, judging by his outlandish attire, he's some sort of free-thinking anarchist. Smithers: I'll call security, sir. Mr. Burns: Excellent.
