Half the people are going to think it's an orgy and everyone will be disappointed.
It's a reference to the book Hitchhiker's Guide to the Galaxy where:
a) the number 42 plays a significant role b) the towel is hailed as the most useful thing a galaxy hitchhiker could possibly posses.
So Don't Panic and don't forget your towel :)
