snakes, dinosaurs, and crocodiles (oh my!)

[holden]

What do you think is Karl's and Rick's fascination with scaly reptilian tracknames? (ok, dinos aren't really reptiles, but you get the picture)As we know, many of the tracknames are random tidbits that might have little to do with the contents of the track (DA3D for example, though i still think of a computergame dino running around when i hear that bassline!), others are a bit more literal (King of Snake re: snake fighting).
Is "crocodile" a reference to "crocodile tears" (i.e. faked emotion, false sympathy, etc)? The lyrics do sound pretty earnest, though maybe its ironic?
And just listened to "Phonestrap", where Karl sings "Here comes snake face".

Maybe it's just like the 'boy" and "dog" that are in many of the lyrics, but i think all these creepy crawlies mean something more significant.
Any thoughts?
