I think I've got a winner here. The Evergreen State College "Geoducks." Pronounced "gooey-duck."
Here is the fight song:
Go, Geoducks go,
Through the mud and the sand,
let's go.
Siphon high, squirt it out,
swivel all about,
let it all hang out.
Go, Geoducks go,
Stretch your necks when the tide
is low
Siphon high, squirt it out,
swivel all about,
let it all hang out.
.....and here are a couple of images. Yes, there's some pretty impressive meat hanging from these little fellas but don't be intimidated. The 'neck' is not a sex organ. Usually.
