Wow, using the phrase “moving treadmill” three times in three consecutive panels seems like bad writing to me. If you have to signal the setup for a joke so obviously, it’s probably not a very good one, and you probably don’t have too much faith in the intelligence of your readers. Like, if he’d referred to it as just “the treadmill” once or twice his readers would have been too confused and not understood that Funky hurt himself.
I always wonder about the genesis of these storylines. I assume this is something that happened to Batiuk in real life. I do wonder if he replaced “Flash action figure he placed on the treadmill to pretend it was a Cosmic Treadmill” with “Discman”.
Oh, and telling a story at AA about how you had to interrupt your exercise because you needed “a drink” so bad that you ended up injuring yourself and (presumably) a prized possession seems problematic.
