If you don't get it, you need to read Robert Heinlein's "Stranger In A Strange Land". It's an excellent book!
Another design I did for my nest mates and spiritual family who've been part of the Church of All Worlds for ages or just associated with the Clear Lake based Nest we hang out with for a long while. They went nuts with the bad grok puns at a recent meeting and some decided they would like to have some of them to wear at the upcoming Beltain campout. Sooo, being artistic, having access to a source for such t-shirts and loving a good joke, I volunteered. This idea was suggested by my friend Liz and I latched onto it like a pit bull. XD This far it's my favorite. You can see this and the other designs in the series as they are added to

Sorry to be a bother but, what is a grok?
Because it is not often I hear or read that.
But this is nice.

Borrowed from Robert A. Heinlein's novel, Stranger in a Strange Land, "Grok" is derived from a Martian word meaning "to drink" pure knowledge until it's deep within our molecules. *Grins* I Grok it...I really do!
