There are crabs at the beach

In this conversation, I explain to Mike that although I am tired of getting emailed by creepy men from myspace, I still want my profile to be public. He starts talking about crabs.

Megan: i turned my profile back to public
Megan: couldn't handle the isolation of friends-only
Mike: haha
Mike: aww
Mike: how romantic
Mike: you're addicted to possibilities
Megan: someday my prince will come
Megan: that is so true!!!
Megan: haha, that's my new quote
Mike: thats what the whole internet it about right?
Mike: i mean its why you have to check email and have to be on aim and have to let the world see your myspace account
Megan: i guess
Mike: but
Mike: lets talk for a moment about crabs.
Megan: um
Mike: if you want to find crabs, you go to the beach.
Mike: odds are, there are crabs at the beach
Mike: but if crabs are what you really want
Mike: than you probably shouldnt look in a cornfield
Mike: the point is,
Mike: myspace is a cornfield
Megan: so what's the beach, o wise one?
Mike: lifes the beach
Mike: and by beach
Mike: i mostly mean be-ach
Megan: hahaha
