Shawn (about Lauren's letter): How could you let Topanga read this?

Cory: I am a Valentine's Day veteran, Shawn. I march in the parade.
Eric: He's a bad, bad man.
Shawn: I get so depressed around Valentine's Day.
Cory: What's depressing about Valentine's Day, Shawn? Especially when you have a girlfriend to spend it with.
Shawn: Okay, first of all, I have to remember it. It's not like Christmas when you have all month to think about it. I'm still cleaning up after Groundhog Day, and I turn around, and the mailman gives me a Valentine.
Cory: From who?
Shawn: From the mailman! And, of course, I didn't get him anything and I can't really tell him it's in the mail.
