Where energy comes from

A couple more:

Simon was jumping up and down on his bed yelling, "I have energy! I have energy!"
Jeff asked, "Where did you get all that energy?"
Simon answered, "From me."

Simon: "I'm catching a frog". (while hopping around the living room)
He smacked into the wall, then told me (while rubbing his head), "I'm done catching frogs now."

Simon spilled water all over the floor. His eyes wide, he said, "Uh oh. I'm in big trouble now!"
