I’m sure he meant he was standing near the toilet when a snake shot out of the bowl like a rocket. :)
She meant.
Mother had run out of the bathroom yelling there was a snake in the toilet and refused to go back in. Grandpa poured gasoline down it saying that’d take care of anything down there (his solution to everything). There was a bunch of white gunk bubbling up so I sat down on the floor and had my head in the bowl. BAM! Out shot the snake which was going crazy everywhere sending everyone running. Mother to the dining room. Grandpa to the kitchen. Me to the living room. Grandpa later admitted to hearing things in the bathroom and putting a rock on the toilet lid to sleep at night.
