I can only recommend to make comedy
natural rather than unnatural, which most people will find not funny but just bizarre. I read the script and yes it has some moments but generally it is not so funny. I also perhaps see why it is untitled - the only title that comes to mind is something like "Abused Claw Strikes back" or something like that, which itself is probably not so funny at all.
i think you have a nice setup with the broadcaster (Jack), his female boss (4

and the younger female colleague (29). One can think of many funny situations that may happen between 3 of them, like rivalry between the women for another broadcaster, who is nice and attractive (not Jack, but another male character, say Robert, who might be an athletic and sporty type) and both may try to get Jack on their side. Jealous Jack, however, may secretly spoil plans of both of them, to get their affection and to prank the attractive broadcaster (just an example).
For example, when Robert reads news, Jack may give him some completely crazy text, which starts as normal one (so Robert doesn't notice anything at start) but then has some crazy parts, which Robert has to read on live news, just to spoil Robert's work.
