I've had a few. I remember one quite vividly...This was a couple of years ago so I was about 16. I was at Macy's about to try on some jeans. Seeing the Men's section, I walk in and start looking for a free changing room. All of a sudden a girl, 20 years of age, hot as hell, in her underwear might I add comes out. She looks at me, giggles, and tells me that I'm in the wrong dressing room. I didn't know what to say. It turns out that from where i was standing the "wo" part was cut out, so I only saw "men". I also walked into the girls bathroom a few times...but the best was when a girl walked into the mens bathroom, that was awesome.
