Funny Harrisonism

While driving to church tonight for a committee meeting, Harrison was chatting up a storm and I just wanted to write it down so that I can remember it.  It went something like this:
H:  Mom, I have sooooo many girlfriends
Me:  Why, yes, you lucky little guy, yes, you do Harrison!
H:  But they can be soooo annoying!!
Me:  What?  Why would you say they are annoying, you love seeing all of your friends!!
H:  Because I have lots of sleepovers with girls and they always wake me up!
...(sleepovers??? This is news to me!)
Me:  Oh really?
H:  Yes, and I was in (pause...pause...)  light bulb sleep and they kept waking me up!
Me:  What exactly is light bulb sleep?
H:  Its when you sleep so hard that you sleep like a light bulb
....it took me a minute and then I just couldn't help but laugh when I realized that he was trying to use the phrase "out like a light".  It always makes me laugh when they try to learn new phrases to use.  I'm sure he was sitting there trying to think about how sleeping was like a light bulb, and it somehow made sense to himself.
