Hailey came to the clinic complaining of vaginal irritation. She was seen by Gregory House, who quickly diagnosed her with bacterial vaginosis. Hailey told Dr. House that she didn't tolerate the pill well and her boyfriend didn't like wearing condoms, so they were using jelly and she wondered if that was causing the problem. Dr. House thought she was talking about contraceptive jelly and went to dismiss the suggestion, but as he looked up he saw she was carrying a jar of strawberry jelly. House was baffled by how she confused strawberry jam for contraceptive jelly. He then stated that she had neurological problem, leading to her ask if there was something with her brain (not realising that he was subtlety calling her an idiot), which he confirmed.
To tick off Eric Foreman, who was his temporary attending, Dr. House called him for a consult. He took a swab to confirm vaginosis and let Dr. Foreman have a whiff to see what he thought. When Hailey asked when she could have starting sex again, Dr. House told her "From an evolutionary standpoint, never", another subtle jibe at her stupidity.
