Graham's Up the Tree! ("and there's nowhere else he can go!") - my 4 year old ran around the house for weeks misquoting the story with his own interpretation of an Australian accent. Calling it out over, and over, and over again.
It's Weinerman Sam with his weiner schnitzel fam,
Putting sausages to bed like a good fam-i-ly man.
Doing ev'ry thing he can just to get them into bed,
For a restful night of sleep in a warm bun made of bread.
The man with a vast red hat met a flower on the pad and asked, "Are you my dad?" The flower said, "No. I'm not the one, but I'll pretend I'm your dad if you'll pretend you're my sun."
