Spammers ... seriously?!?

The spam emails I get are always so obviously spam, I just have to wonder how it is even worth their while to keep spamming. Let's just take a walk down the chain of thoughts that someone would have to have to actually respond as the spammers desire:

<Moron opens his email>
Moron: Oh! I've got a new email! Looks like it is from ... me?? Hmm, that's strange. Oh well, I'm sure there's a good explanation. Let's see what this is about...

<Reads subject line>
Moron: "I'm your new manager"? What? How am I my new manager? Maybe I work for myself now! That would be great! I guess I'd better read it or I might get fired.

<Opens email>
Moron: Is there supposed to be something in this email? Oh, wait ... here's some words: "Can't see the images below?" I certainly cannot! What should I do? Oh, it tells me - "Click here" Okay!

<Clicks on link>
Moron: What's this? A website for buying erectile dysfunction medication from overseas pharmacies? Now why would I send myself an email with links to a site that sells ED medicine from overseas pharmacies? I guess I'm going to start a business retailing cheap ED meds. Better buy in bulk!

Seriously, what other chain of thoughts would possibly lead someone through the courses of action that end in a win for the spammers? Not only are the deceptive tactics completely lame and unbelievable, they are also completely disjoint along every step of the way. Come on!
