Your mom

While you're going to think who would be your test subject with your ray gun, the door to your room opened as your mom walked in.

"Oh, honey, are you making one of your robot models again?" She said as she tried to look over your shoulder.

You looked up at her. "Mom, can I get a little privacy?"

"Oh, sorry, dear. I'll just get out of your hair now..." She said as she turned.

You turned your head to look at her. As you been thinking, you wouldn't mind your mom be your test subject to try this gun.

"Oh, Mom, there is something you can do for me." you said and you ready to pull the trigger.

She turned. 'Oh, what is it, ho...' Her sentence was cut off just as she was zapped by you quickly.
