Wednesday's Mark Trail

Ooooohhhh, that's some dog-on-Mark action going on there in panel three. Andy's well-trained to know that Mark needs it bad when he gets home. I'm guessing that in the non-existent panel four Andy gets slapped away and told, "Now now, Andy!"

Or not. What's really scary, besides the possible bestiality, is Chucky Rusty in panel two. It's like he's about to throw an ax at Mark and then eat his brain.
