Well she is my niece, but close enough right
My parents were watching my 4 year old niece. They had just recently bought a German Shepherd puppy, and he wasn't yet house trained. He always got a little excited with new people around and had a bad habit of peeing on the floor when excited. So someone new comes in the house, Gunner peed on the floor in the kitchen, and my dad, without thinking said "Ah, Gunner pissed on the floor."
Didn't think anything of it, until my sister (my niece's mother) came home. Aislynn (the 4 year old) promptly tells her mother in a proud voice that "Mommy, Gunner hissed on the floor!!"
My dad didn't know whether to be embarrassed or just laugh. Aislynn still claims that they "hiss" when they pee
