I've done that to my kids!Pretty much every time we pulled up to a railway crossing you could count on my Dad pulling this one out:
Dad: "A train just went by..."
Us (rolling our eyes): "Sigh.....how do you know?"
Dad: "It left it's tracks..."
Apropos of the dayTopical Dad joke:
My next door neighbour just popped round with her dinner on a plate. Facebook and Instagram are down, and she needed to show me what she was having...!
