It happens.
BTDT.
One day, mother went in to use the toilet and immediately came out hollering about a snake in it. No one believed her but she kept on and on about it. Grandpa got tired of listening to her so went to his solution for everything - gasoline. He poured a gallon down the toilet and a bunch of weird white stuff came floating up. Of course, I sat down in front of it, rested my arms on the seat and stuck my nose in to see what the stuff was. About that time, a six foot racer shot out and hit me square between the eyes knocking me back and was going crazy trying to slither up to the ceiling.
I ran to the living room and jumped on the coffee table. Mother followed to the couch. Grandpa was left alone in the bathroom hollering for someone to shut the door. Miss Prim and Proper Mother told him to shut the @(&^_(*# door himself. It was an old farmhouse so the door was several inches above the floor so the snake came at us in the living room.
Grandpa later admitted he’d been hearing noises in the bathroom at night and had put a rock on the toilet lid.
