On the other hand, we know from the oracle that Belkar has less than a year to live.
Oracle has made mistakes before
I really liked this strip, and I cannot really get how people are saying it wasn't funny. Admittingly the comic isn't just the standard joke-of-the-day format, but it really is better off that way. Great jokes come from great build-ups. And quite frankly, I've laughed a lot harder at the humor from character interactions - interactions that happen because of character building - then I have about the throwaway D&D jokes that I forget when I'm done reading. And as someone said, the fact that the whole point of this strip is to purposefully poke fun at a long standing cliche is a level of humor it couldn't have made if all it did was say "Har har the wizard has low charisma, isn't that just like a wizard?"
There are dozens of webcomics on the internet that are all about D&D jokes and geek humor. And most of them, quite frankly, aren't really that good. Throwaway, joke-of-the-day comics get old, and they get old fast.
