so, not only has this person given away their username and password to the entire world, allowing anyone to log onto twitter and pose as them, but they've also alerted everyone as to where they'll be at a particular time (so someone could either find them there or, more likely, find them absent from their home). might as well hang out a sign that says "want to rob me? i have an opening on the 29th at 4:30pm"
there are a number of issues covered in this comedy skit, and i like how it highlights how gullible you have to be to fall for some of the attacks out there.
really, there's more to this than just the comic - you should read the associated blog entry as well. the artist/author has some well founded doubts about the entire concept of going to some arbitrary website and having it supposedly clean your computer.
the theory behind the captioning at There I Fixed It was that the gate latch was added to the car because the numeric code (see that panel above the door handle? that's for entering a passcode) is too hard to remember.
the thing is that the gate latch isn't a lock, it's a latch. if a latch alone was good enough the owner could simply close the door and not lock it (also, you can still use traditional keyed entry judging by the keyhole). it appears that this car door is in such a state of disrepair that it won't actually latch properly and needs to be held closed with this additional hardware. so the true moral of the story is that both security technology (the lock) and the infrastructure it works with (the door) need to be maintained or they won't do you any good.
