I Can't Catch My Legs In Ten Words

I can't catch my legs,
When rolled into a ball

I can't catch my legs,
Magician sawed me in half

I can't catch my legs,
Train is dragging them behind

I can't catch my legs,
Since the aliens probed me

I can't catch my legs,
I'm too busy eating them

I can't catch my legs,
They're running much too fast
