Suspiciously Specific Denial/Playing With

Basic Trope: A character denies a hypothesis so detailed that there is no reason to think of it were it not true.
 * Straight: When Alice finds Bob on her computer and asks, "What are you doing?" Bob says, "I'm not changing your desktop!"
 * Exaggerated: "I'm not hacking the Nielsen ratings to make curling appear more popular than hockey! I'm just ... uh, updating my resume."
 * Downplayed: "I'm not browsing the Internet -- I'm just keeping it from going to sleep!"
 * Justified: Bob is a Bad Liar.
 * Inverted: "Calm down! I'm just jiggling the mouse so your computer doesn't go to sleep!"
 * Subverted: "I'm not ... uh, what did you say I was doing?"
 * Double Subverted: "...well, whatever it is you think I'm doing, I'm not doing it!"
 * Parodied: ???
 * Deconstructed: Bob really wasn't doing what Alice thought he was doing.
 * Reconstructed: ???
 * Zig Zagged: ???
 * Averted: "Just a sec -- I'm not done pranking you yet."
 * Enforced: The thing being denied is the central element of an Ignore the Disability gag.
 * Lampshaded: Alice replies, "You realize I never said anything about my desktop, right?"
 * Invoked: Bob doesn't want to admit to constructing a computer virus, so he states that he is not changing her desktop around...which is actually true, but makes Alice think that's actually what he's trying to hide from her.
 * Exploited: Could Say It, But....
 * Defied: When Carol hears Alice come in, she interrupts Bob before he can blurt out anything incriminating.
 * Discussed: "The secret to hiding something is not to deny its truth, but to pretend to know nothing one way or the other."
 * Conversed: "This character's such an idiot. If he were more vague with his denials, he wouldn't end up in the doghouse every single episode!"
