How many librarians does it take to build a fire?

I doubt that anyone will every hear this as the entry line for a comedian at Zanies or the Comedy Club. This is the true expression of a neurotic need to organize. This, coupled with former training as a Boy Scout (to become a Tenderfoot scout you had to build a fire with only one match--Tenderfoot is the first rung and if you couldn't pass this, well, let's just say, there were no other campouts for you!), and you've got a scary situation on your hands. STEP AWAY FROM THE MATCHES......
I hope this image gives you a chuckle, because it gave everyone else one! I guess more than my foot was a little tender......

By the way, the answer is one and the joke isn't that good...
