I like Sharp as a Marble - he's got a very good sense of humor, and a wry outlook on life (at least as he presents himself on his blog).
This post - Why I'm Thinking About Boycotting "Brain Fertilizer" - is just a little bit of fun he's apparently having with a blog-buddy, Brain Fertilizer. They have a silly exchange which is a fun example of some of the ridiculous hilarity possible between blog-friends.
I like this stuff. I like having "family ties." Life can be serious, but these guys remind me that "fun" is not a four letter word! LOL ;)
