Zack, here's how I would have liked them to make them funnier for me, basically playing with the last panel punchlines. It's just IMHO.
09/18/03 Z1 The tooth fairy one. In the last panel you can add "...but I still have a tooth for you under my pillow."
(Notes: In Mexico we don't have a tooth fairy, we have "Ratón Pérez" (a mouse) to take care of fallen teeth. About two of the 09/19/03 ones, I don't have an opinion because we don't know too much about the Dixie Chicks or la fée verte. Same thing about the 09/24/03 one about Klarsh.)
09/19/03 The Info Show 1. In the last panel you can add the mother (an old lady) of the smelly stickman, to show he still lives with her. She can say something like "You are getting too thin. Eat your broccoli."
09/19/03 Z2 The one about fire. As it is, the message is more frightening than funny. I'd add "This is just a comic, so I'll be back."
09/24/03 Z3 The one about smoking. You can combine the first and second panels in one panel, and divide the third panel in two. This would build momentum for the smoking dinosaur.
09/25/03 "Woa. Way powerful!" To the victim's lines I would add "It was just a simple question, man!."
10/08/03 "The You-are-so-ugly show". The last dialogue implies that "Mr. Ugly" came to the show even if he already hated it. Better if he said "No wonder I was hating this show so much", which allows the possibility of him being surprised at the last minute, not really knowing what the show was about.
And about the most recent one, "The Info show: ZacarÃas". Here the happy face of the kid in the last panel doesn't help. It would be better to use "none" as a character, his dialogue coming from off-screen. Readers would think that he was dragged off the set against his will.
This is one possible way, IMHO.
