The 4th one was my favorite.
IMHO, "stating the obvious" punchlines don't work as stand-alone jokes. There needs to be something more than just wacky absurdity there to counteract the statement. I humbly offer one of my own comics as an example:
[Click to view comic: 'OPC51: RadÃkovice Council On Tourism']
Here, the joke is that Radikovice didn't, for some odd reason, mention something as obviously fascinating as talking dinosaurs on their Wikipedia page, even though the town is (at least judging by this strip) crawling with the yakkity buggers.
But hey, like they say, "Humor is like a frog - dissect it and it tends to die". Take what you like and throw out the rest.
