Funny / Lupin III vs. Detective Conan: The Movie

• When Conan grounds Ayumi, Mitsuhiko, Genta, AND THE PROFESSOR for getting themselves into trouble. He might've just been talking to the kids, but the older man choruses a defeated "haaai" right along with them.
• When the elementary school students are captured snooping, Lupin's group divests them of their belongings, and the resulting group of miscellaneous gadgets and Noodle Implements they had on them is ridiculous.
• Most of Jigen and Conan's interactions.
• At the very, very end there's a fake teaser for LUPIN III vs. KAITOU KID: The Movie, slated for 2020. Then Conan appears in a bubble over the alleged movie's logo to inform the audience that it's a joke.
