Why I Love My Job

Conversation between me and one of the grad students in the lab today:

Me: Why are there fish from the grocery store in the freezer?
Grad Student: This is a fish lab.
m: uh huh...
gs: They're silversides.
m: and...
gs: But they're selling them as smelt, which is not even the same family! And they claim to have caught them in an area where you don't find silversides. So I figured I'd bring them back here, sequence their DNA, and find out what they really are.
m: you know you're the world's biggest geek, right?
gs: No, this is sweet. It's forensic ichthyology!
