Once tried to drown a stinkbug and washed it down the sink drain one night and went to bed thinking I was safe... It was just sitting IN THE SINK the next morning like oh naw get an exorcist and a flamethrower I'm not dealing with that demon
One time i just happened to be looking at my bathroom sink and a giant water bug crawled up out of the drain. Rare occurrence, I believe, but I kept the drain closed when not in use for about a month. Skeeved me out!
