I can top that.
I was sitting on the toilet at workplace bathroom, and I saw a small cockroach walking in the back corner, behind the toilet. I wouldn't be comfortable doing my business with that thing around. There was a plastic cup sitting on the floor (what the hell are people using it for??), so I went ahead and put the cup over it. Time passed and I completely forgot about the incident. Then about two months later, I was in a similar position when I remembered about the cup. I looked behind the toilet, and there it was, still upside down. I went ahead and lifted the cup, and the damn thing SPRINTED out like it had been waiting for its chance for two damn months. In complete darkness. Without any food or water!
Needless to say, I let it live. It earned it.
