The two main reality shows that aired last night were based around sex: which skanky single would have it with Bret Michaels on Rock of Love; and which teammates would hook up on Big Brother. Let's find out!

Rock of Love: The "divine nine" wake up and Big John hands them their next clue: it's time for the second annual Bret Michaels Mud Bowl! Catherine the cougar is excited, because she's a dirty Montana girl. Daisy is terrified of getting hurt, probably because she's really tiny. -- Buddy TV

Big Brother: Allison threw out an ultimatum very early in the episode where she basically told Jen that she'd tell the house about her secret if Jen was disrespectful to her at any point in the game. Is it us, or does Allison seem way too defensive about the Jen and Ryan relationship? -- TV Squad
