I'm bouncing off the windows

I'm bouncing off the windows.
I'm bouncing off the walls.
I'm feeling like my feet are made
of bouncing rubber balls.

I'm running like I'm crazy.
I'm running like I'm mad.
I might seem like a lunatic
but,boy,I'm feeling glad.

I'm jumping like a kangaroo
or like a jumping bean.
I act this way at least a week
right after Halloween.
