I'm pretty sure I stole this joke from somewhere, but I can't remember what it was. It might have been the scenes in Star Wars where Han thinks the hyperdrive is going to work and they get all worked up, and then nothing happens, much like in this comic. But those are such memorable scenes, you'd think I'd remember if that's where I stole this joke from.
Then again, maybe I stole it from Star Trek: The Next Generation, where the Enteprise has built this super death-ray to use against the Borg, and they end the third season with a cliffhanger, where they're going to use it, and then the fourth season starts with them firing, but, oh, it doesn't do anything. Hmm... but that's not quite right either.
Oh well. I'm sure I'll figure it out sooner or later, and then I can go back and edit this commentary!
