Knock Knock

Heh-heh-heh-HEH-heh
It's a laugh we all know
Maniacal and funny
A machine gun banter
It brought so much laughter
To me on a Saturday morn'

Heh-heh-heh-HEH-heh
With a wild eyed expression
And your victims' distress
At trying to sleep through the night
Your relentless persistence
Kept me coming back for more

Now I'm old and quite tired
With a home of my own
Is it a cartoon come to life?
On Saturday morning
With uncanny timing
Heh-heh-heh-HEH-heh

You're back in my life
