House, MD: the new case

“The patient is showing symptoms of early-onset optimism and unseasonal excitement. We need to find out what’s causing this before it’s too late. Differential diagnosis people!”

“Positive emotions can be increased by prolonged exposure to the sun…”

“Prolonged exposure to the sun… in February? You moron!”

“Studies have linked mood swings to the lunar cycles…”

“Yeah. If the patient turns into a wolf, I’ll let you know.”

“Perhaps the patient is just having a really enjoyable week?”

“No, there’s only one thing to blame here…”

“Start the treatment.”
