Me: "Please don't stand on that moving toy car"
Bubba: "but I like it"
Me: "No, please get off, it will topple over and you'll hurt yourself"
Bubba: "why?"
Me: "because it'll move and you'll fall off"
Bubba: "Why?"
Me: "why will you fall off or why will you hurt yourself?"
Bubba: "why?"
Me: "just trust me, I've asked you a couple of times so please get off!"
Bubba: "why?"

The most annoying bit is when I really haven't got a clue why or I want to stop the 'why' so I just use the universal mum code...
"Because I said so..."
The funniest 'why' was at 4am when bubba turned up in our bed and needed to know
"How do worms poo?"
Me: "well like us, our their bum"
Bubba: "why haven't I seen it!"
And sleep...
