Your last keg?!
That's perfect! Really. Now when people show up you say, "sorry, dude number three and his wife kicked my last keg and I haven't had time to brew. You know, it takes 6 hours plus a couple of weeks, not to mention all of the time spent cleaning everything. To say nothing of the cost of the grains, and hops and yeast aren't free either. Nope, it might be another 3 or 4 weeks before I have anything ready to go . . . "
Then see who keeps coming around to hang out.
