According to TVSquad.com, "The CW is actually growing slightly on Fridays with their one-two punch of 'Smallville' and 'Supernatural.' They even managed to tie a Fox show."
"[The Good Guys] may have beaten 'Supernatural' (0.4/2, 1.18 million) in the hour, but it tied in both viewers and the demo with 'Supernatural' on the night, and you don't tie with The CW if you're one of "The Big Four." Even if you were just throwing a repeat out there on a Friday as filler."
