I'm currently totally enthralled in the demon-hunting adventures to be found in "Supernatural." I just finished the second season, am waiting for netflix to send me the third one, and am mostly caught up on the current fourth season.
The show is basically a never-ending male-bonding road trip revolving around two seriously attractive brothers who drive around in a totally awesome car, listen to a steady stream of classic rock, and... oh yeah... hunt demons and other supernatural baddies while trying to connect with their rogue father who has spent the last twenty years being singularly obsessed with tracking down and killing the demon who murdered his wife and burnt his house down.
Most episodes find the brothers investigating paranormal crimes (most often grisly murders), lying through their teeth with only charisma, fake IDs, and occasional costumes (see photographic evidence below) at their disposal.

Dean Winchester? Easily one of my favorite tv characters ever.
Here's a quick sample clip that not only showcases the funny, but a little bit of the brother interaction as well:
And this seriously cheesy link's for my friend C. and her remarkable ability to capture hilarious screen captures of attractive men, because the middle of the video features approximately 30 back-to-back shots of Dean pouting:
