Showering

Panel 1: (A shower cubicle) Theorem: For any positive integer n, there exists a justification for going n days without showering. Proof: We proceed by induction on n. Panel 2: (The mathematician) Base case: n = 1 Most people shower once per day. Right before you shower, you have gone 1 day without showering. If going 1 day without showering were unreasonable, you would have showered before then. Panel 3: (The mathematician in front of some paper) Induction step We assume the induction hypothesis is true for n and now consider the case n+1. Suppose you have a problem set or an exam next day. Clearly, showering can wait 1 more day until you get that done. Panel 4: QED Man: I'm not going near you ever again. The mathematician: The best part is I use the same argument to justify not going to sleep for just 1 more hour.

Despite much of this comic being autobiographical, I promise this one isn't. Really.
