Don't worry if this installment's in-jokes whoosh overhead; sometimes I write to amuse no one but myself. I'm not even sure this one makes sense. I'm also probably overly optimistic about my future hairline in Panel 2 but, since I'm time traveling anyway, I figure why not hope for the best.
I have no doubt that when I eventually gain the ability to time travel, I will be my own worst enemy.
Next Day Edit: Changed a few details, including the final punch line. I like Crazy Old Coot Brian. Might see him again.
