I shouldn't laugh, but that sounds like something out of a tv or movie! And it's really funny!
No, it's completely fine. My family is full of weird "TV/Movie moments".
My dad's favourite is we went to New England Patriot's games when I was little. Maybe Maddie's age. One time, we were sitting next to these big middle aged men who were completely out of their minds drunk.
And one of the guys next to us spilled his beer on me and was cursing.
So I turned to him, got his attention, and said: "What would your mother think if she saw you right now?"
And my dad broke out laughing.
Now two decades later, he won't shut up about it. It was literally the first story he told my husband when they met. As if to say "hey, you're marrying this..."
