I probably don't come out of this well
In my third year at university, I came home with a couple of my housemates to find a strange bag in the living room. In the spirit of "it might be a bomb or something, better check" I opened the bag, and the first thing I found was a fine pair of frilly red ladies' pants. Being the emotionally mature fellow that I was at age 20, I proceeded to have a bit of fun with said item of underwear, wearing them on my head and generally larking around. Suddenly housemate #5 appears from nowhere with a young Spanish lady in tow, presumably the owner of the aforementioned knickers. I managed to hide the evidence just in time as she picked up her bag and the two of them retreated into his room for sex. Later on, when they went to shower, I snuck into his room and replaced the pants in her bag. I'd totally got away with it.

Unfortunately housemate #2 had written up the entire incident in his diary, which housemate #5 found lying around the living room a few weeks later...
