I Need To Go Iron My Dog / Anime & Manga

• Bleach plays with this: when everyone but Orihime want to leave class to stop hollows/arrancar/whatever the enemy of the arc is, they give excuses that could work if it was the first time (the teacher doesn't seem to mind, though). Orihime tells everyone the truth (not in a Sarcastic Confession way) about exactly what she's going to do, but since she imagined herself as a robot before she got spiritual powers, enjoys making horrific amalgamations of foodstuff, and is just a general Cloudcuckoolander, nobody believes her and thinks it's her imagination going crazy once more.
• In Bungo Stray Dogs, Atsushi has just heard that there might be a mole, and realizes that Mister Tonan is lying to him. He ends up flustered and then quickly excuses himself by claiming that he has to go feed a chameleon.
• Dragon Ball: In the Majin Buu Arc, Son Gohan spouts a flimsy excuse to leave class, change into the Great Saiyaman and track Videl down before she engages some bank robbers.
• In FAKE, one kid tells Bikky "I gotta go home and feed my mongoose." Another says he has to help his sister with her homework. Given the kid's intelligence, Bikky finds the two equally implausible.
• In Fullmetal Alchemist (2003), Wrench Wench Winry goes gaga over Ed's State Alchemist watch and begs Ed to let her borrow it. Ed refuses since he knows she's just going to take it apart to see how it works, and he doesn't want anything to happen to his badge of office. So Winry tries to turn on the charms with Major Alex Armstrong. He resists enough to use the trope ("I think I'll go chop about a year's worth of firewood...") so he can leave the room.
• Attempted by the Tachikomas in an episode of Ghost in the Shell: Stand Alone Complex. After discovering that they're going to be facing up against anti-tank helicopters that they'll be virtually helpless against, they try to avoid it by complaining that (despite being robots) they need to go back to base because they have stomachaches. Batou doesn't buy it for a second.
• Once Teana arrives to visit the hospitalized Subaru in Magical Girl Lyrical Nanoha StrikerS, Erio and Caro quickly depart from Subaru's hospital room, loudly telling her that they'll go buy her some hot soup from the cafeteria.
• Medabots: When Ikki, Erika and Metabee pretended to be students of Rosewood Academy to sneak in there and the doorman asked why they weren't wearing their uniforms, they said they spilled caviar on it and their butler would bring them later. (It was a school for rich kids) The Screws tried the same excuse but Kikuhime/Samantha (their leader) ruined it by stating they spilled caviar on their butler.
• My Next Life as a Villainess: All Routes Lead to Doom!: Season 1 Episode 08, Catarina gets sucked into a magical book along with Geordo, Nicol, Keith, Alan and Sophia, where she gets bounced between the others' increasingly elaborate romance fantasies, from Geordo's wedding night to Nicol's dramatic flight with her to Sophia pushing her up against a wall in her personal library to confess. Once rescued, they learn that the book was playing out said fantasies for witnesses...and the next few seconds are dominated by sentiments like "I need to get going" and "oh, look at the time." (Alan, whose romantic fantasy never got beyond the opening bars of his song, is mostly just confused why everyone is acting so embarrassed.)
• In Nyaruko: Crawling with Love!, when Yithka asked why she didn't simply ask for Nyarko's help rather than going with a "Freaky Friday" Flip plan as her first resort, her response is "Well, now that I've finished giving out my exposition, it's time for me to go!" and runs out of the house at top speed.
• In episode 2 of Ojamajo Doremi Dokka~n!, Hana-chan yells "Toilet!" during class. Rather than using this to actually go to the bathroom, she uses the excuse to play pranks on the students using her magic.
• Pluto: When Atom and Gesicht have a conversation in a restaurant, Atom excuses himself to go to the bathroom. Gesicht points out that they're both robots, to which Atom claims that it became a habit to be more human. It's actually because Atom read Gesicht's missing memories, and ran away to cry.
• The girls of Powerpuff Girls Z had to come up with excuses when they were summoned. The first excuse was pretty understandable, but they would then degrade to these by the third one.
• Pretty Cure:
  • Tropical-Rouge! Pretty Cure:
    • In episode 25, Manatsu says she needs to use the toilet when a Yaraneda is attacking the school, and Sango and Laura agree. This was used as an excuse for the girls to go outside of the school to transform into Pretty Cure.

  • In Delicious Party♡Pretty Cure episode 6, Kokone and Yui say they need to use the toilet to try to see if the monster some students saw was related to the Bundoru Gang.
  • An episode of HeartCatch Pretty Cure! had Tsubomi and Erika stuck with some of their friends during a monster attack. As their friends were wondering where the Cures were, Erika attempts the weak excuse "We're gonna go now..." before they're stopped and told to stick together. It gets to the point where Tsubomi's ready to put her foot down before Yuri shows up to fix things. As for Itsuki, she was busy trying to warn everyone away.
• Ahiru of Princess Tutu tries to do one of these, but...
  Ahiru: Yeah, that, that! Well, see you later...

• In episode 20a of Tamagotchi, after Lovelitchi and everyone besides Mametchi sing a song to get a special cherry blossom tree blooming, Lovelitchi thinks Mametchi should sing next.

• Yu-Gi-Oh! GX: In "Field of Screams Part 1," after Crowler and Banner both try to back away during the call for volunteers and bump into each other, Crowler seemingly volunteers to duel Camula when he leaps forward as a reflex action. A sweating Crowler says that they should draw straws to decide who duels Camula, then insincerely bemoans how there aren't any straws and says that he'll go to get some and that they shouldn't follow him. The others don't buy it and tell him to go out and duel her.
