Now what do I do?!?

I happened to be present when a stand-up comedy novice asked a seasoned veteran about what kind of merchandise they should start selling at their shows. The veteran very tactfully explained that that is not the kind of thing an aspiring comic should be concerned about at this stage in their development. He said it's far, far more important to concentrate on writing good material and learning to be comfortable on stage. In other words, worry about your act and not the non-essential and silly things that ultimately don't matter. This would include not only anything having to do with merchandise sales but also 'wacky' stage names and stupid catchphrases. All that stuff is completely unnecessary.
It's excellent advice, but what am I supposed to do with 24 cases of these?
