17. "Night Call"
Nothing makes us more appreciative of the advancements in phone technology (specifically call screening) than Season Five's "Night Call." At least it'd be nice to have the option of letting your dead husband leave a voicemail before losing sleep over a series of creep-tastic phone calls characterized by a bunch of eerie static and moaning. That said, if you're blessed with the ability to dial your former boo from beyond the grave, we'd love to get the name of your service provider. Verizon, perhaps?
