Usually I'm pretty serious here, but this is a good one... it's a polka medley of a bunch of Christian pop and rock songs, a la Weird Al:
Highlights: "Kiss Me" (Sixpence NTR), "Fireproof" (Pillar), "You Are So Good To Me" (Third Day), "I Can Only Imagine" (MercyMe), several more.
Make sure you click the "enoshfett" link for a couple of songs from Enosh's band, and this is the link to his main site: http://www.enoshfee.com/
Enosh is a friend of mine. His commentary on the song: "Not too bad for about an hour's work!"
