I was in a gas station this morning and the guy in front of me bought a zig-zag cigarillo. I always assumed that they were strictly for stuffing with marijuana. It turns out the guy is attending the class I am teaching. Can I assume that my lesson may not be sinking in with him as well as some of the others or is that a legitimate cigarillo? Do they even have tobacco in them or are they just empty tubes? If he's high, I want to fuck with him.
