Think before you speak

I opened my mouth and a foot fell out.
Again,
 I hadn't looked before I spoke.
If I'd been a car
You would have wrecked me,
Over a cliff perhaps, so you could watch.


Would I have eaten my own words as I fell?


I opened my mouth and a foot fell out.
I wish you'd used one on me,
Before I could speak,
Before I could....Well you know.


If I open my eyes now, will you have gone??
