Knock knock

[Chameleon Creator]

I need a knock knock joke for my fiancé, it has to do with electricity.
I know this has nothing to do with chameleons but I know there are plenty clever people on here that can help.
She needs it for her third grade class.
Thanks guys

So much pun

Sorry not knock-knock jokes but...

Q. Why do fluorescent lights hum?
A. Because they can't remember the words.

Q: Why did Mr. Ohm marry Mrs. Ohm?
A: Because he couldn't resistor!

I'm sure I could generate some more of these, but I'll leave that to someone else.

Not kid appropriate or a knock knock joke but had to say it:

Why was the light switch mad?

Because someone flipped him off!
