I read a Young Justice tie-in comic where Joker ended up taking down half the Justice League before Batman beat him down. My favorite part was where Martian Mad Hunter tried to telepathically take Joker down and just seeing his mind incapacitated him. Joker doesn't show up much in Young Justice show because lots of fans complained about the voice actor. Mainly that he wasn't Mark Hamil therefore he was miscast. Point is, on some level I dare someone to intrude on thoughts I will force so many annoying songs to be stuck in your head forever. If I ever face a telepath my go-to defense is Hamster Dance.
German always sounds harsh. It can never sound friendly or alluring... Of all videos from Postmodern Jukebox this is probably my all time favorite leg...I mean song. My favorite song! Along the lines of harsh languages. You know how in fantasy and sci-fi fantasy movies they usually make the bad guy race's language sound really menacing no matter what they say? If I was writing a comedy parody I would have to have orcs speak menacing and play with the subtitles and have them talk about wholesome things in a menacing way. Kah rash nak torah! Nak rak gooral na! (So we got the macaroons your wife made and my family couldn't get enough of them! Why did they did taste so good) Tesh rak nop toray! (The key is to add orange zest) I've been wanting to use this joke in a written piece but this is really a gag that can only work in the medium of a live action film or television show.
