Another "deleted" strip. You'll find that, towards the end of this run of strips, discarded comics became a fairly frequent occurrence. Why was this particular strip given the axe? I can think of several reasons off the top of my head. First, it's not really that funny. Second, it doesn't have Sporkman in it. Third, it relies upon in-jokey knowledge of Rob's fate. That third reason is probably why it ultimately didn't make the cut.
Interestingly, this strip was 100% completed back in 2005, inked and lettered. Pulling it from the lineup was apparently an eleventh hour decision.
