The entire department is obsessed with lesbians today, even more so than usual. One of my colleagues, an overtly bisexual female, yesterday used her personal laptop to run a class. She was showing the class some website or other, but with one slip of the mouse she managed to display a bookmarked website entitled Lesbian Erotica, indicating more about her lifestyle than she'd planned.

Ironically, the lecture was on professional presentation skills.
