Here's a few. I'm only posting the ones that I could solve by myself. I'm pretty sure the site I got them at is the same as the one shy sakura did, since it has all the ones she posted.
Turn us on our backs
And open up our stomachs
You will be the wisest of men
Though at start a lummox
Bury deep,
Pile on stones,
My mind will always
Dig up them bones
It occurs once in every minute
Twice in every moment
And yet never in one hundred thousand years.
What has roots as nobody sees,
Is taller than trees,
Up, up it goes,
And yet never grows?
Voiceless it cries,
Wingless it flutters,
Toothless bites,
Mouthless mutters.
It cannot be seen, cannot be felt,
Cannot be heard, cannot be smelt.
And empty holes it fills.
It comes first and follows after,
Ends life, kills laughter.
