Serious Breakfast Conversation

Had a serious conversation about jokes over breakfast this morning.  How many good jokes do you know?  When is the last time you told or heard one?  The funny thought raised serious concern, when I realized how joke starved the world around me seems to be.  Not to say this funny matter in of itself is all the serious, but what it represents unnerves me.  If I haven't learned to make people laugh, then what have I learned?
