You and your husband, Max, had came to pick up your son from football (soccer) practice. While the two of you were waiting for your son to pack up, somebody insulted him, yelling

"YOUR P-NIS IS THE SIZE OF A TIC TAC!"

the kid yelled, you and Max look at the kid, about to tell him off when your son responded

"THATS WHY YOUR MOM'S BREATH SMELLS SO GOOD!"

Max immediately cracks up and covers his mouth, lowering his head. You yourself had managed to hold back a shocked laugh, and you glare at him, and smack the back of his head lightly.
