T-Rex: That's right, everyone! Once you realize that copyright only starts counting down when an author dies, you realize you've just been given MOTIVE... FOR MURDER!!

T-Rex: And I just told you exactly that, so no take-backsies now!!

T-Rex: So now we ALL have motive! And we ALL have means too, since to do a murder all you have to do is tie someone to the train tracks, and we all learned how to tie our shoes, AND THERE'S NOTHING TO PREVENT SUCH A KNOT BEING USED ON OR ABOUT THE TRACKS OF TRAINS?? Which means...
T-Rex: ...we are all now SUSPECTS.

Utahraptor: Aha! A murder mystery in which anyone could've done it!
T-Rex: Yes!!

Utahraptor: Well, that's actually been done too.
T-Rex: No, see, I'm doing it in REAL LIFE. I'm going to an authors group to explain how everyone present is now a suspect, and then if any authors DO die, the police will suspect...

Off panel: ...you and all your friends?
T-Rex: Yes. Wait. I messed up somewhere. Man! Murder IS hard!!
T-Rex: BUT IN BETTER NEWS, I JUST CAME UP WITH AN AMAZING TITLE FOR MY NEXT STORY
