What are your best (or worst) stories of pretending to be straight?

One time in Mandarin class, the teacher asked me in front of the whole class who my celebrity crush was. I panicked slightly, and said the actress who came to mind, which ended up being Mila Kunis. He just laughed and patted me on the back before I speedwalked back to my seat clearly quite flustered.What ridiculous things have you done to convince someone you're straight?
