They should be. Look at what I found in my mailbox today (I ordered it maybe two days ago):
Syntax of Things is responsible. Yes, those are maggots. On the reverse you will find that sad/funny Richard Ford quote JRL mentioned a few days ago. You too can get a magg-bagg, or a tee-shirt, here. I don't, by the way, have any idea who the Syntax of Things guy is -- no kickbacks! -- but I do like his blog. And his bag.
* A couple of years ago, Megan Daum wrote an essay called, I think, "Music Is My Bag." It was about how she gave up music as a teenager because of music-geek culture -- because of the "music is my bag" totes and piano key scarves and so on. I don't remember much about the essay, but, in the weird way certain phrases can stick with you for no good reason, I've thought of "________ is my bag" about once every two weeks since I first read it. It's really annoying, actually. Maybe using it as the title of the blog post will finally purge it from my mind.
