How Did That Get in There?

A stock phrase and one of those Blatant Lies...

Someone is flipping through a slideshow, PowerPoint presentation or book of photos and has a slide of something they shouldn't, or that makes them look odd. Someone might points it out and they'll say "How did that get there?". Sometimes it works but usually not. Of course, sometimes it's just being spoken in Sarcasm Mode.

Frequently accompanies Porn Stash.

Anime and Manga
"Ranma: I'm disappointed in you though. Ya switched to Ryoga just because of cherry blossom marks? Akane: It's your fault for not eating a cake! Ranma: Who can believe somethin' so silly? Akane: What's that in your hand? Ranma: ...How'd that get here?"
 * Kodachi Kuno of Ranma 1/2 has been known to do this. The time she hid tacks in her hand before shaking Akane's hand comes to mind.
 * Another example would include the time when Akane tried to get Ranma to eat some magical sakura mochi that could tell whether or not they were destined to marry. Because he doesn't want her to find out that he's going to actually try it, he takes one when she's not looking then goes to eat it in peace. Unfortunately, he forgets himself when he sees Ryoga happily skip away after giving Akane flowers...

Film

 * Austin Powers and the "Swedish-Made Penis Enlarger Pump". It's not his, despite the credit card receipt. And the warranty card. And the book about his life with it. Which he himself wrote. The pump becomes a Running Gag, making a appearance as a Chekhov's Gun in the final scene with Random Task. Sure enough, Austin's still trying to claim it isn't his.
 * The Mask: While being frisked by the police, the Mask says he's never before seen the pair of funny-eyeball glasses that come out of his pocket. The bazooka, on the other hand: "I have a permit for that."
 * Russell Thompson, Sr., uses this line word-for-word near the end of Honey, I Shrunk the Kids after his wife finds a pack of cigarettes in his baseball cap.
 * Death at a Funeral: "Oh My God! What are you doing in my dad's coffin?!"
 * Subverted in the movie Gung Ho as auto manufacturing plant manager Michael Keaton feigns surprise that a not-really risque photo of a woman appears in his slide show about the plant's personnel. The woman in the photo is actually part of the management team.
 * In The Hairy Bird, Mrs. Dewey finds the Porn Stash planted in Mr. Dewey's briefcase.
 * In Jackie Brown, the title character reacts to ATF agents finding cocaine in a bag she was carrying with "What's that shit?" (although it's implied that she really hadn't been aware that she was carrying it).

 * In The Worst Week of My Life, when Howard tries to steal the concrete-encased corpse of his fiancee's family dog (long story). It doesn't work at all.

 * At a Ring of Honor show, Colt Cabana pulled double-duty, wrestling earlier in the show using his masked "Matt Classic" persona.

Cabana snatches it away with mock-surprise, and says "How did that get in there?"
