In his funniest minute-and-a-half on television. I found this on the cwtv site and thought my fellow Supernatural fans would enjoy it as much as I did. Unfortunately I can't give you all a direct link....
go to the above address. Then click "preview and more" on the right hand side and select "Supernatural Presents: Jensen Ackles".
I believe this dailie/clip was taken from "Yellow Fever" (S.04 ep. 06)
I hope you all enjoy it as much as I did!!
