The one where he rhymes:
"John and Mary sitting in a tree,
K - I - S - S - I - N - G,
First comes love, then comes marriage,
then a unexpected, tragic miscarriage,
John leaves Mary and takes the tree,
D - I - V - O - R - C - E."
So mean, yet so funny.
I think it was done by Kris, its an oldie, at any rate.
