Calvin and Hobbes by Bill Watterson for October 21, 2015
Transcript:
Calvin: The aliens still haven't shown up! what are we going to do?? I've got to turn in my leaf collection tomorrow! Calvin: I'll bet those dumb aliens got back to their planet and procrastinated! I'll bet they have no respect for deadlines! I'll bet they put everything off and are doing a lousy job at the last second! Hobbes: How could anyone be so irresponsible? Clavin: If they're not here in five minutes, I'm not handing over the earth! they've got to learn a lesson!
Perhaps because the aliens are stuck in intergalactic traffic Calvin, its awfully busy from mars to earth.
