Astatue of a Macho athlete was displayed in Museum, Husband and wife came walking there appresiating and arguing everything they saw so far.
Husban would not let wife win the battles of wits.
so wife relaxed watching this nude statue with just a couple of leaves to cover it's privates, hoping husband goes to other displays. The husban says, " Marvelous, but really darling there is not much to appreciate her.
What is it that you are waiting for?
Wife says' " Dear, the season when the leaves FALL "
